How to lay it flat when unroll it?
Generally, it flats quickly when put on the desk or table. If it can't flat, please heat the protector with a hair drier or other way until it become soft then put a basin of water or heavy books on it.
Please Note:
The clear pad is a bit sticky at the surface, it will create air bubbles on stoving varnished, marble or glass tops. Recommend for Matte pad instead.
