Thank you for viewing. This is high-quality square conte chalk. It's an easy-to-use 6mm square type, and by changing the angle, you can draw lines from thick to thin, and also fill in areas by laying it flat. After use: We recommend using a fixative (setting spray) after drawing. If you frame your artwork, please be careful that the drawn area does not touch the glass. * Although it is new and unused, it has been stored at home for a long time, so it is listed as "no noticeable scratches or stains." Please refrain from purchasing if you are concerned. - Colors: Black, Brown - Quantity: Set of 9 boxes (Black x 5, Brown x 4) Not sold individually - Size: Approximately 6mm x 6mm x 65mm - Uses: Drawing, sketching, illustration, design, etc. - Shape: Square * Shipped in simple packaging via Nekopos (a Japanese delivery service). * Please also see my profile.
