My own little creation, born out of box weave with fins added to the sides and then stitched up in HP 3 in 1. Very flexible. Entirely in Stainless 7/32 18g SWG.
A few HP 3-1 stretchy bracelets I made for myself. The top 2 were some of the first pieces I ever made. Bottom 4 are alternating weave directions made a couple of days ago. Note the difference in size. They all have the same number of rings. Shows that they will stretch out over time.
