This is a brand new Anti-Static Mat for Table or Floor sealed in plastic and canvas wrapping which is 2' x 4' (24" x 48"). It is a Grainger-approved product from Zoro Select. It is a green nitrile rubber mat that is .138 inches thick. It has a grounding snap in one corner and black rubber bottom that prevents slipping.

I also have these in cases of 6. Please check my store if you are interested in bulk purchase.
