Therefore, the product made from the return sheet is poor in quality and performance, then in the purchase of time, how to identify the new acrylic sheet and return sheet?

2. Is it easy to scratch:

The return sheet scrapes more easily than the all-new transparent acrylic sheet, so you can touch it to see how the surface hardness of the transparent acrylic sheet is.
