Finally found something good to wear on my right wrist!
I had to go hunting to find these, eventually ordered from a shop in the UK. Only silicone wristbands I've ever seen with the actual /flag/ pattern rather than the ugly "color blotches in a circle" design.
If anyone wants a set, here's the store I got them from: https://www.ebay.co.uk/itm/NON-BINARY-LGBT-Pride-Silicone-Wristband-Bracelet-NEW-FLAG-DESIGN/232892035458?hash=item3639727182:g:xSYAAOSw~FlbdTCH
