I made a flat pouch using laminated fabric. It's water-repellent, making it ideal for storing items you want to keep dry. In the second image, I've put an A6-sized planner inside. It's also useful as a mother and child health handbook case, a bankbook case, a pen case, or for storing small musical instrument accessories like reeds and tuners. Regular-sized masks fit inside. Approximate size: 15 x 20 cm Do not wash. It's a stain-resistant material, but if it gets dirty, wipe it with a damp cloth. Includes shipping via Mercari. Mask pouch Floral pattern
