A whole piece of paper with individual patterns and colors, after cleverly tailoring and sewing, transforms into a lightweight, stylish and durable Mighty Stash Bag, which is a good helper for collecting small items such as change, keys and lipstick. 25% of the raw materials come from recycled milk and beverage packaging, which is a veritable eco-friendly design. The ultra-thin Mighty Stash Bag is a humanized design. Designer Terrence Kelleman specializes in exceptionally thin and tough Tyvek specialty papers as a raw material for Mighty Stash Bag. Waterproof, lightweight, and tough, it is resistant to tearing, abrasion, and folding. With zipper opening design, it is safe and easy to handle. http://www.youtube.com/watch?v=3SgN5lMWVeY Product specifications Material: Tyvek. Size: Approx. 10.1 (L) × 10.1 (W) × 10.1 (H) cm.
