I know the rose isn't black, but that is the name of my favorite arc in Revolutionary Girl Utena where these rings where used by the "villains."
According to the series, Duelist Rings change their color after their owner's death. In the Black Rose arc, non-duelists where manipulated & given the rings of deceased duelists so that they too could compete for, win, then kill, the Rose Bride. Fascinating, isn't it?
But anywho, I used Shrinky Dink plastic to make the ring. It's all one solid piece of plastic with the insignia (my icon xD) printed on. I can make different ring sizes using different sized metal tubes. Right now the only size tube I have is a five, but I'm considering buying more so I can start taking orders when my classes end in December.
If you think you might be interested in ordering come December, you can leave me your ring size here so that I know what size molding tubes to buy.
Here's the size chart I'll be using [link] fyi, you can place one of your rings over the circles, whichever circle is the same size as the inside of your ring is your size :'D
"do something about it"? I sense a deviation
Wow, you're making rings!
All the best with your business venture!
Thank you~
good luck with selling those, anyways)
