Sofft 65100 Knife & Cover Mix Instant purchase OK. Although not new, it has been used very little. Each of the blue knives has a number, and you use the corresponding numbered cover (tip) by placing it on the tip of the knife. It's convenient for drawing with PanPastel, mixing colors, and blending colors. * The number sticker is missing from the #2 cover only. * Each cover contains 10 pieces. Also, there are sticker marks on the cover outer bag (images 4 and 5). Please also check the other conditions in the images. Thank you for viewing.
