Collaboration between ONE PIECE and HELLO KITTY. Featuring Hello Kitty and Chopper from One Piece only. Envelope & Sheet Seal Set (A special envelope and seals designed to match the envelope's pattern are included). Envelope size: approximately 14.5cm tall, 21cm wide. I likely acquired this around 2012 (I think it was from a gashapon machine). There is some fading due to aging, but there are no folds or stains on the envelope. All the seals are unused. Thank you for looking.
