Review on Self Adhesive Handwriting Management Electronics Computers Multi Color by Andy Hearshman

I've been waiting for this for 4 days and now I have to buy it at the stationery store. The material has a "plastic" (?) texture that is difficult to describe and almost impossible to read afterwards. Tried it with a felt tip pen and a ballpoint pen. If you just want color coding which I don't have then they're fine, otherwise I'd take something else.
