Dice Rolling Tray. Flannel and PU leather Hexagonal Dice Tray
This awesome dice tray will keep your dice landing a little softer and a little more on the table.
It is small enough to where it wouldn't take up too much table space, but big enough to be able to roll your dice into.
5" across at it's widest points, and about 2" walls (these measurements are when it is clipped into place)
It does lay flat for transport, so it can fit right in with your books and notes.
