The Spinning Ring.

(Flash Contests Ring's)

• Fashionable design,
• Prints as one piece (requires support),
• Very strong design,
• Great fidget tool,

Would also be great if the inner and outer were printed in contrasting colours to show it off better. 

Update: 2 hours later and the ring is still on my finger as I can't get it off and don't want to break it.
