LONGONI Blue Diamond Chalk - 2 pieces - New Personally, I use this chalk because it feels smooth but has good grip. As it is chalk, there may be some cracks or chips. The box may have some minor stains. No price negotiations, no claims, and no returns (e.g., if it's different from the image, or the color is not to your liking). Prices may fluctuate depending on stock availability. Please refrain from unnecessary greetings, comments, thank-yous, or notifications in the comment section, as they can cause confusion. I will not do business with those who do not understand Japanese or with foreigners. Thank you for viewing.
