This is a bag that came with the JR East Attendant Licca-chan doll, which I believe I purchased through mail order several years ago. It's approximately 27.5 cm tall and 18.5 cm wide. It seems to have a gusset, but I'm unsure as it's unopened. The item is also vintage, so please be aware that the plastic bag may have wrinkles from storage. Thank you for your understanding. Instant purchase is available. TAKARATOMMY Takara Tomy Licca-chan JR East Attendant Doll
