Thank you for viewing! (*´꒳`*) This is a handmade pouch with a gusset. Interfacing has been applied to the outer fabric, giving it a moderately sturdy construction. ☆☆Please note that this is a handmade item, so there may be some imperfections such as歪み (distortion) or slight stitching errors. I have sewn it carefully, but it is not perfect like a mass-produced product. Please refrain from purchasing if you are looking for perfection. If you understand and appreciate handmade items, please consider purchasing! ☺︎ 〈 Size 〉 ◎ Height: Approximately 13cm ◎ Width: Approximately 20.5cm, Gusset: Approximately 4cm ◎ Uses a 20cm zipper "Please understand that there may be slight millimeter-level variations." #HoneyTune #MaskPouch #RetroPouch #HandmadePouch #CosmeticPouch #PassbookPouch #HoneyTune #ShowaRetro #DiaperPouch #MaternalAndChildHealthHandbookPouch #SmilePouch
