This is a ring that holds its shape around your finger. If you can figure it out :P
Whats good about it, is that it doesn't look like a puzzle ring but it still takes you an average of 10 seconds to randomly figure it out - though i had some friends that gave up trying...
I made 17 sizes using the United States and Canada system without the quarters.
For finding your own ring size start from Wikipedia:
This is size 0 other available ring sizes are in my shop.I personally think that the red one is the most playful.
