I just know from what I've seen in the bag. I love to use faux pearls in a mix design on my nails with silver caviar beads. These look really nice, I only bought one size I think.. not sure because I had caught the end of their summer sale I believe and everything was unbelievably marked down!
After a good look over though, no damage, nicely flat back, exactly what I wanted.. very happy with my purchase. I will always recommend RB
