These bead tubes are the best I've ever used, and I've used a LOT of different tubes.
The highlights: The plastic near the top does not crack with repeated opening, the "lid" is strong, the hole used for hanging doesn't split, and the tubes *stay* closed.
I bought the 4-pack of tubes first, and they were so good I bought 50 more. You cannot beat the price--24 cents per tube.
I use these to store round seed and Delica beads; I also use them for daggers, cubes, drops, Tila beads, etc. I'm looking forward to having all of my seed beads (and shaped beads) hanging on my pegboard!
