This is an original bag designed with the concept of "simple, lightweight, functional, and yet unique"! Like the phases of the moon, you can change the shape of the bottom by attaching and detaching the buttons. The main fabric used is upholstery (velvet) from foreign chairs. It's durable and won't damage your clothes when you go out. When washing, please be careful of shrinkage, wrinkles, and discoloration, and we recommend hand washing or dry cleaning. For daily care, gently brush with a soft cloth or a clothing brush. Magnets are used for the opening, so please be careful as bringing magnetic cards or passbooks close to them may cause damage. ＜Details＞ Outer fabric: 70% rayon, 30% polyester (made in France) Lining: 100% cotton (made in Japan) Size: S Bottom width 30cm, Opening 24cm, Height 20cm *Shipped via Letter Pack Light.
