So I have probably a half a dozen or so of these and abiut as many regular fly cups as well. I don't tie with beads that much but when I do I only use 2 sizes 3/32 and 1/8. So I use two of these to put said beads in and organize them by color. I have a few others to put my "less than perfect" flies in as they are still useful but I don't feel they are worthy of my regular boxes lol. Like I said they are handy as ever, OH! And I have on I store my odd hook styles in I don't use as often, and two more for glass beads for midges and soft hackles. They are bigger than you'd expect, I just put right at 50 size 16 soft hackles in one yesterday, organized by color of course, and they barely made a dent.. You won't be disappointed thats for sure.
