Their custom hoppers were based on clear shells with the design on the inside, and I’m not aware of a clear Rotor shell.
I had one produced which was a clear apache shell with any custom logo inside and then painted white. It’s still alive and functioning after 10 years but doesn’t get much active use
There are a few people about who have produced custom hoppers and can be done via a number of methods such as hydro dipping, painting, vinyl cut logos etc
