About KitpasQ : Is it safe to put Kitpas into the mouth?
A : Kitpas is a safe product as it meets chemical characteristic of Chapter 3 in EN71 “The Safety Standards of Toy”. However since it is solid material, it may become a cause of choking if it was put in the mouth, especially for small children. Please monitor small children from swallowing it. In case the Kitpas was accidentally ingested, drinking a glass of water or milk may help accelerating egestion if less than one piece was ingested. However, we advise to please contact physician for advice, if the child doesn’t feel well or feeling nauseous. If the Kitpas was licked, please gargle thoroughly. If the child is unable to gargle, wipe the tongue off and clean inside of the mouth with a wet towel.Q ： Can you wipe off the scribble on the surface of the car or on metallic surface made with the Kitpas?
A : It is possible to draw with the Kitpas onto any kinds of surface. However, depending on the condition and the characteristics of the surface, it may be difficult or impossible to wipe it out completely. In addition, if the scribble or the drawings are left out for a long time on the surface, it may stick to the surface and will become impossible to erase. Therefore, DO NOT draw on the surface of the car or on metallic surface with the Kitpas.Q ： Can you use Kitpas to draw on a paper?
A : You can use Kitpas almost like crayons and it will produce great color. If written on a regular paper, it cannot be erased. However, because Kitpas is water-soluble, you can use it like water colors with a drawing brush to make smudge effects or mix colors. Be creative and have fun!Q ： It was explained on the instructions that you can easily erase the drawings made with Kitpas on the glass surface or the white board. How about on the regular blackboards?
A : If surface of the material is rough, such as wood, papers, blackboards, plastic blackboards, it is difficult to erase the drawings completely. Therefore, if the drawings must be erased 100%, please do not draw on that material.
If drawn on a flat and smooth surface, such as glass or white board, it can be erased. However, when the drawings are left un-erased for a long time, it may stick to the surface and will be difficult to wipe out depending on the material. Therefore, it is recommended to try first on the inconspicuous area of the surface before actual use. Although it is not guaranteed, in some occasions, drawing Kitpas over the previous drawings may help erasing the original drawing.
A : Fixed grimes on the surface of the flat and smooth glass may cause the drawings hard to erase later. In addition, if the drawings on the glass will be left un-erased for a long period of time, or when it’s exposed with dew condensation, rain, and water vapor and then dried out, it will be difficult to erase. In such cases, use a detergent with abrasives to scrape off or melt it out with a polish remover. To scrub it off with pencil eraser might also work.
DO NOT draw on a frosted glass or a glass surface with special kind of films pasted because the drawn particles will get into the bumpy surface which would be hard to erase.
A : DO NOT draw on wallpapers (same for wallpaper made of vinyl material) because the oil component of Kitpas will be penetrated into the wallpaper and become un-erasable.Q ： What should we watch out for when we draw on wire glass with Kitpas?
A : DO NOT draw on wired glasses with Kitpas, especially with dark colors such as black etc., because the glass may get heat cracks. It is especially dangerous if Kitpas is used heavily on broad areas. Heat cracks will happen due to the temperature differences within the window between surfaces where the glass is exposed with the sun light and where it’s hidden under the sash of the glass window/door. This temperature difference will cause the “heat crack”. This phenomenon is more likely to occur when the glass is thicker and the area is broader. It is also said that wire glass is more vulnerable to this phenomenon.Q ： How can we clean the stains made with Kitpas on skin or clothes?
A : You can wash off the stains on skin and clothes with water or water with soap. If it doesn’t come off easily, such as when the Kitpas has been stained into the deeper part of the fiber etc., soak the clothes in warm water with detergent for work clothes for about an hour, and then hand wash it. If the stains still remain after these steps, please seek help with a stain removing professional.Q ： Will the scribbles made with Kitpas be printed off from a whiteboard with printing/copying ability?
A : In most cases, it will be printed, but there is no official experimental data available to support that. We advise to please try and see for yourselves.Q ： Will the Kitpas melt during the months when the temperature is very high?
A : PLEASE AVOID storing the Kitpas under the direct sunlight, or inside the car when it’s under the blazing sun, when the temperature is over 50 degrees Celcius (About 122 degree in Fahrenheit). If it’s left at a place where it has more than 50 degrees in temperature, the Kitpas may soften, but when it’s back to regular temperature, it becomes usable.Q ： What’s the difference between “Kitpas (incl. Kitpas Kids)” and “Kitpas for construction”?
A : There are not much of a difference between the two, especially with their main components. However, Kitpas for construction is created for the outside use such as at a construction site; therefore, it is more water-resistant than a regular Kitpas.
Diameters of the Kitpas is the following:
Kitpas, Kitpas Kids: About 11mm
Kitpas for construction : About 8mm
A : It is alkalescent (pH 7.5) and not acidic.

About Our ChalksQ : Would my hands get rough and dry by using chalks?
A : Ingredients of the chalks won’t make your hands rough and dry. If you leave dust or powder on your hands for long, it will deplete the fluid from your skin and your skin gets extremely dry. Therefore, if you plan to use the chalks for a long period of time or if you have a sensitive skin, please use either hand lotion to protect your skin or “chalk holders” that we sell separately.Q ： Chalks will easily break on a rainy day for some reason. In addition, the colors come off very easily and we feel troubled.
A : Most commercially available chalks lose strength extremely after absorbing water. Please try not to make it wet. For rainy weather, we also sell “Rainbow Chalk” which is made of plasters and it is more water-resistant. Another new item, “Water-Resistant Chalk” made of calcium carbonate will be on sale from April 1st, 2016. This product has better erasability compared to Rainbow Chalks.Q ： Is there a chalk product that you sell which I can write on whiteboards?
A : Unfortunately, none of the blackboard chalks (Dustless Chalks) we sell can be used on whiteboards. However, Kitpas (solid marker) can be used on whiteboards. (Kitpas cannot be used on blackboards. After using it on whiteboards, please erase it with either wet cloth or special cloth.)Q ： I have some allergies to ingredients of chalks, can I use Dustless Chalks?
A : Current Dustless Chalks contain no casein which can cause allergies or formaldehyde which can cause sick building syndrome. Some people worry whether the dustless chalks cause any allergy symptoms from scallop seashells, which is one of the ingredients of these chalks. Please do not worry since we use extracted calcium carbonate portion from the seashells only by processing it through high-temperature calcination treatment and clearing impurities. Because this calcium carbonate is main constituents of bones and teeth, it is rare and not possible for it to become causes of allergies even if taken into the body by any chance.Q ： Can we write on asphalt (blacktop) or cement/concrete surface with “Dustless Chalks”?
A : It is possible to write on asphalt(blacktop) or cement/concrete surface with Dustless Chalks, but depending on conditions of the surface, it may stick and remain forever, so please do not use it on the surface where scribbles cannot remain forever. Even when drawn on a surface where a few scribbles left won’t be a problem, it is recommended to quickly wash it off with water and a brush after use.Q ： Are egg shells used as one of the ingredients in Dustless Chalks?
A : No, we don’t use egg shells as ingredient of Dustless Chalks.
About the BlackboardQ : Would my hands get rough and dry by using chalks?When I use chalks on a new blackboard for the first time, the marks from chalks will stay on the blackboard after trying to erase it off with erasers. What should I do?
A : New blackboard surface is rough and has many tiny bumps, making it easy to be clogged and powder can stick to the surface and remain as a thin layer. In order to smooth out the bumpy surface, lightly and thinly draw with the chalk on the whole surface of the blackboard; then, erase it evenly with eraser to blend it into the blackboard.
*We recommend you to use the longer side of the chalks to draw thicker lines when aiming to draw on the whole surface of the blackboard.
*Surfaces of similar products of ours, such as “Small Black board (A4 size)”, “Tiny Black board (A5 size)”, “A bit large Black board (A3 size)”, “Notebook type Blackboard”, etc., should also be treated with chalks to smooth out the surface before use.
