Thank you for viewing! This is a Fujiya Peko-chan keychain. It was stored in its original packaging, but I opened it because the bag was dirty. It has not been used, so it is listed as new and unused. There is no keychain chain. m(__)m The size is approximately 6cm tall and 4.5cm wide (at the outstretched hands)! If you would like to cherish it, how about it? (^^)
