This dice tray is lined with green velvet, which feels soft to the touch, unlike hard, scratchy fabrics. The sound of rolling the dice is significantly dampened, and the table remains scratch-free. I don't have to worry about the dice robbing or damaging the surface, making it incredibly safe to use.
I measured it, and the unfolded size is pretty much as described on the product page. It takes up absolutely no space in a school bag or board game bag. If I go to a friend's house and try out the DND, I just snap the buttons on the four corners and start rolling dice. No worries about the table being slippery or the dice floating around. It's so practical.
I immediately unfolded it flat, and the metal snaps at the four corners snapped shut, transforming it into a square tray. No more dice rolling off the table. It takes less than five seconds to fold and use—a real bonus for lazy players, allowing me to focus more on the game. Such a thoughtful design!
