I bought these beads to make a family bracelet with all of our initials. They are good quality beads. The lettering is defined well so you can actually read my bracelet. I strung them on two strands of 2mm black leather
from Auntie's and it went through just fine. The beads don't have the rough edges that some do, so my leather has stayed nice. I added crystals between them. The crystals were the birthday color for each initial (had to use fishing wire for those). Turned out really cute.
