My Melody Keychain - Retro I believe this was likely an accessory that came with something else. It's an unopened item, so I think it's very rare. Besides My Melody, there's a charm of a yellow flower basket attached. I can't confirm clearly because it's unopened, but it seems the production year is listed as 1998. Size: My Melody part - approximately 4cm Title... Sanrio Sanrio / Character Name... My Melody Item / Type... Keychain
