Clay Studio Tables
Well I believe this is just the weight we are looking for to cover our 3 large tables in the clay studio! We will be ordering!


Very Heavy material! Love It!
This is the heaviest material I have found. This batch is for special tool bags for myself and crew. After waxing, this should hold up great. Definitely worth the price. You won't be disappointed! Michael
