This doesn't seem to have a name in the chainmaille community, but it's a very satisfying fidget -- the small rings are smooth on your fingertips, and the whole thing flows in a lovely way. My son's partner has one on their phone case to play with.
This fob is a riff on Daniel Quasar's evolution of the traditional and Philadelphia pride flags, which includes stripes for trans and non-binary folks, as well as for people of color. It's my favorite pride flag, so you'll see its motif on other items in my shop as well.
