SLAP BAND GLASSWARE
2016, ICONIC CONCEPTS
Set of two pint-sized glasses with a unique metal "slap-band" collar that fits around each glass rim. Slap-bands were a trendy accessory kids were using as bracelets a few years back. The metal band is flat, but when you slap it on your wrist it wraps around and changes its shape into a round bracelet.
Thanks to Tom Mady for the info!
