I have not used them as yet, but I KNOW they will solve the dilemma I had in the focal beads floating around the bracelet. I have leather, charms, spacers etc., so now I can complete my projects....once I get back to jewelry making. Working on lampwork beads using the mandrel you sell for these, which I love btw, learning curve yes, but well worth it. Dianne
