The women who use/used them in the traditional sense would often break them to give to daughter or whomever, I don't think the maker ever attempted at fixing the "bubbles" I think they live with them the way they turn out, I have seen horrendous examples to absolute masterpieces, many with manufacturing flaws, they become a unique part of the character of the individual bead as you yourself noted, I think it's a great bead! As far as wearing them goes, I consider myself the caretaker of the beads I have collected and the Kiffas happen to be some of the more fragile beads I own, so I personally preffer them to not be strung and worn. I leave that choice to the owners of the beads. I again want to thank you for showing them, they are beautiful and your wife is a good cherrypicker! Thomas
