It is about twice as thick as a mouse pad & you can drop metal dice on it and not hear a sound. It is necessary for metal & gem cut dice like Gamescience.
This mat is large enough for more than one person to use at a time. It has excellent sound deadening qualities and allows us to play on a wooden table without damaging the table or waking up the other people in the house. Great product. Highly recommended.
I gave the mat to my son. He loves the design and appreciates a nice surface for his gravity dice. The colors are really vibrant
