I need your help.
I have found in a second-hand store a material that seems to be a compact synthetic felt.
After some research, it seems to be used on a cutting table. I hope the picture will help you identify the material.
It's 4 mm thick and the length of the roll seems to be 2445 mm.

Do you have any idea what is it and where could I buy some?
