So sorry SaraConr just saw your question. I honestly don't know & don't have anything to measure with. But they fit on leather cord & pandora bracelets. Hope that might help. I also have 2 more auctions with more of these.
Hmm. Well I make beads into ornaments for dollhouse Christmas trees. Since the scale is 1 inch = 1 foot, an 8mm bead is perfect for the bigger ones and 6mm and 4mm for the smaller ones.
