This is an interesting classic styled Sonic item. It's a pair of figural Sonic cufflinks. Each one is 3/4 relief sculpted. They appear to be metal, painted with enamel. They're shaped like classic running Sonic, and are quite nicely detailed!

They can be found at NEXT stores in the UK in 2011. As you can see at left, they came in a nice box with paper tag at the bottom. The 'background' has space for the backs so they display well. MIB photo by SonicTeam.
