I joined this drop on a whim the first time and like the rolling trays so much I just joined again to get additional colors! I play D&D with a large group, and we're all always looking for good rolling solutions. In the past I've made some out of cheap wooden boxes from craft stores, and while those serve fine, I don't have enough for everyone. I have several sets of MDG's engraved gemstone dice, so I know the quality of their products tends to be top notch. These rolling trays are great; I don't find them too large for my crowded table, and these are perfect for rolling metal or gemstone dice. I also took them with me when I played as a guest in a friend's game out of town, and they are so easy to transport. When flat, I snap the two trays together so the velvet interior has some extra protection during transit.
