Thank you for viewing! (*´꒳`*) This fabric is made with cotton flecks, so there are small black specks! This is not a stain. (See photo 4) 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) and uneven stitching. I sew 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 12cm ◎ Width: Approximately 20.5cm, Gusset: Approximately 4cm ◎ Uses a 20cm zipper "Please understand that there may be millimeter-level errors." #JollyPom #jollypom #RetroAnimal #MaskPouch #RetroPouch #HandmadePouch #CosmeticPouch #PassbookPouch #Panda #ShowaRetro #DiaperPouch #SmilePouch
