Review on 🔪 Crafters Companion Glass Cutting Mat: Premium Craft Supplies (13 x 19 Inches) by Carla Anderson

I've been using this mat for a few months now. The first product I received was clearly used. More than 2 dozen deep indentations were cut into the glass. Not only could you see them by running your hand over the surface, you could also feel the sharp edges. The company sent me a replacement quickly and this one had a few nicks as well. I work with polymer clay and do not hit the mat with force. I noticed that over time, more and more deep grooves developed as I used the mat. I wouldn't recommend this for any hobby. Either the glass is not properly tempered and there are scratches from cleaning the surface, or it's just a bad product and a waste of money.
