Sanrio Hello Kitty Envelope Set - 6 pieces (Likely from 1991) Features the early Sanrio logo pattern. Originally came with 8 envelopes, but 2 have been used, so there are 6 for sale. The stickers are unused, but their adhesive quality is not guaranteed. One envelope has stains and marks. Please check the photos. There may be other overlooked imperfections. Please understand that these are vintage and pre-owned items, and are stored at home for a long time. Thank you for your understanding.
