This white iron away pencil works on dark to black fabrics. It is makes clear neat marks and won’t accidentally brush off but will be there on the fabric until you iron it away completely like magic, with no residue. AWESOME! it is 17cm long and never needs a sharpener, you just uncoil its paper body which is kinda fun to do. No Panda was harmed in the making of this pencil. You will receive 2 x panda Pencils for $10.
