I decided maybe I was ready for the minor rite of passage of making a dice bag. Here's what I ended up with. The bag is all anodized aluminum except for the closing rings and "drawcord" (all brass), and has stainless steel lobster clasp on the drawcord. It holds 3 sets of 16mm gaming dice (21 dice total) with comfortable room for 3 or 4 extra dice too. Total number of rings = 1332.
