Unused Muji Fabric Crayons, 16 Colors Fabric crayons are crayon-type drawing materials for dyeing that allow you to draw on fabric and dye it simply by ironing. There is some color transfer on the box. ⭐️ Please refrain from price negotiations. The following is from the HP: These crayons allow you to dye fabric by drawing on it and ironing. They are suitable for cotton, linen, and silk, but please test on rayon, cupra, acetate, polyester, and synthetic fibers such as blends of these with cotton beforehand. Wool is not suitable. The iron temperature varies depending on the fabric, so please adjust according to the washing instructions. ・When drawing on stretchy fabrics like T-shirts, it will be easier to draw if you stretch the fabric evenly and tape it to a flat surface. ・To redraw, wash with soap before ironing. However, please note that it will not come off completely. ・Dry cleaning may cause the color to fade, so please avoid it. ・Do not use fabric crayons in conjunction with oil-based pens or oil-based fabric markers. The colors will bleed, and the finish will be unsightly.
