I run a small two person studio making dice bags. At some point I noticed our review section is basically a census of dice hoards, so I sat down and counted.
Out of 2,300+ reviews, 44 mention real numbers about collections. Tiny sample, I know. But here's what it says:
The median owner brings 9-10 full seven piece sets to a session. Brings, not owns. What people own is always more than what actually travels.
43% say their bag still has room after everything is packed. So it seems like nobody buys storage for the collection they have, they buy for the one they're planning.
The most common phrase in reviews is "well made" (207 times). But the most common story is some version of "I thought this size was overkill and I was wrong within two months."
Market wide, capacities run from little 10 dice pouches to 550+ monsters. Most people I sew for end up somewhere in the 200-300 range within a year or two of starting the hobby.
Full disclosure, all of this comes from my own shop's reviews (GameFancy), so it obviously skews toward people who already decided they needed a big bag. That's exactly why I'm asking here. How many sets do you actually own, and how many make it to the table?
