This is a Heisei-retro see-through pen pouch♪ It's a pretty old item. Made of vinyl and secured with a button closure ^ ^ I think it can be used as a regular pouch, not just a pencil case ☆ For those who understand the long-term storage and aging of a private individual, thank you in advance m(._.)m #SeethroughPenPouch #Vinyl #PenPouch #Pouch #KamioJapan
