Flux stock is pretty good at belts but, do you want convincingly realistic belts? Maybe perfect translucent vinyl belts. The resurgence of Patent Leather and PVC in fashion are not a hoax. They are durable and have an infinite lifespan making them circular economy capable, just hand it off to a new user when you don't need it anymore.

See the patent leather, wear more patent leather and PVC

It's good for the environment! (short term manufacturing damages are a lot less than the long term of having an asset that doesn't need replacement for up to 100s of years with proper care)
