Thank you for viewing! (*^^*) This is a handmade flat pouch. It has no gusset and is flat. It's just the right size for storing bankbooks, medical record books, and mother and child health handbooks. It's a perfect fit for a goshuin-cho (temple stamp book) (11cm x 16cm). It's also recommended as a mask case♪ I've added two card pockets (^_^) ◆Size Height: Approximately 13cm Width: Approximately 21cm Gusset: None Zipper: 20cm zipper Opening size: Approximately 18cm * Please note that there may be slight variations m(__)m ◆Interfacing is applied to the outer fabric. #MultiPouch #MakeupPouch #MaskPouch #PencilCase
