I made a necklace out of 4 Sterling Silver curved tubes along with some Czech beads. I've actually made 2 necklaces. They are perfect for the format I used. Sold one of them right away so hope this 2nd one will be as popular. Sorry that I can't get an image to come up to share.
these are great, large opening for stringing - exactly as described!
perfect size for my project, thought they would be too small but the size was perfect,
this tube bead is very nice and fits nicely on 2mm leather cord
