This is an ikura (salmon roe) strap purchased from Kappa Sushi. Size: 2.7 cm diameter, 1.5 cm height. It has been kept in its original packaging since purchase. Although unused, it has been stored for a long time, so the ring connecting the plate and the metal fitting is rusty. The back of the plate is white, but about 1/4 of it has yellowed. The tip of the strap is stained brown.
