Made in Japan, it features a unique formula blending calcim carbonate and 10% recycled scallop shell powder, delivering smoother, clearer lines with reduced dust and shattering. Twice as durable as standard chalk, it’s perfect for professionals seeking long-lasting, eco-conscious writing tools. ## Description A professional choke born from the requests of a cram teacher that is easier to hold and less fatigued. Compared to the traditional JIS design, the thickness of 0.5 inch (13 mm) makes it easy and reliable. The main ingredient is calcim carbonated which is also used for toothpaste, so it is safe to use on the body and is economical for use over twice as long as plaster chalk. In addition, the scallop shells have been successfully recycled, which is a 400,000 tons of disposal in Hokkaido, and contains 10% fine powder of scallop shells. The scallop shell formula allows for softer and clearer drawings, and the particle is heavier and reduces the amount of shattering powder. The handle is coated to prevent dust from getting on your hands. Review: Fantastic - Writes well, a little thicker than the Hagoromo and just as smooth. Item arrived from Japan and not a single stick was broken. Review: Not happy - I was excited for this item because I used chalk paint on one wall on both of my kids’ rooms and this was for them to draw on the walls with. The package arrived with the box open and almost a whole row dumped out in the envelope and broken. You would think there would be tape or a sticker holding the box closed. I am not impressed. Also this is suppose to be dustless. I was expecting some dust but this product is far from that. ## Features - Professional use chalk development by voices from prep school teachers - Diameter of 13mm based on ergonomics idea enables comfortable writing - Durable for long-time use, very reasonable ! - Bold body but writes fine line - Made in Japan ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C56ZF0W | | Age Range Description | Adult | | Artistic Charcoal Form | White Charcoal | | Best Sellers Rank | #457,543 in Office Products ( See Top 100 in Office Products ) #375 in School Chalk | | Body Shape | Round | | Brand Name | 日本理化学 | | Color | White | | Customer Reviews | 3.8 3.8 out of 5 stars (12) | | Drill Point | Broad | | Grip Type | Ergonomic Grip | | Hand Orientation | Ambidextrous | | Ink Base | Water | | Ink Color | White | | Item Diameter | 13 Millimeters | | Item Dimensions | 3.15 x 6.3 x 2.75 inches | | Item Weight | 2 Pounds | | Line Size | 0.5mm | | Manufacturer | Nihon Rikagaku Industry Co., Ltd. | | Material Type | chalk | | Model Number | DCP-50-W | | Recommended Uses For Product | Drawing, Writing | | Unit Count | 50.0 Count | | Writing Instrument Form | Chalk | ## Product Details - **Age Range (Description):** Adult - **Brand:** 日本理化学 - **Color:** White - **Ink Color:** White - **Writing Instrument Form:** Chalk ## Images ![Dustless Professional Chalk (White) - produced by Nihon Rikagaku Industry Co., Ltd. - Image 1](https://m.media-amazon.com/images/I/71otNcq0auL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Is this chalk different than "72 pieces white dustless chalkx3000" other than size? or is it the same stuff, just larger size?** A: Yes, it is the same stuff, just larger size.
