Thank you for viewing! Instant purchase is OK. ★ 16-piece set of heat-erasable chalk pens: red, black, white, and blue, 4 of each color. You can specify all the colors. Please let me know your desired colors in the comments. You can purchase as is, so thank you. If you do not specify colors, they will be prepared as described above. Tip diameter: 3.6mm Body diameter: 5mm Length: 11cm This is a thick-tipped, thick-bodied type. Resin caps are attached to both the front and back of the tip. It has a structure to prevent ink evaporation. The thick tip does not require a holder and can be used as is. This is a heat-erasable chalk pen that can be used on fabric. It disappears with heat at 60 degrees Celsius, so it will naturally disappear when ironed. We recommend testing it on a piece of scrap fabric before using it on your precious fabric. Also, the white one does not show the color immediately after drawing, but it becomes clear after a few seconds when the ink dries. We recommend using it on the lining of the fabric. It will be shipped in simple packaging.
