About the Material (Tyvek)

Tyvek is an ultra-lightweight yet exceptionally strong, tear-resistant material that offers the tactile feel of paper with the durability of fabric. Its water-resistant surface helps guard your belongings from daily moisture and splashes.

Naturally occurring wrinkles are a characteristic of the material and become more pronounced with use, developing into a texture that reflects your personal lifestyle over time.

Please enjoy this evolving wrinkle pattern—each crease adds to the charm and uniqueness of your one-of-a-kind accessory.

Note: Wrinkles are an intentional feature of the product and are part of its distinctive appeal.
