Thank you for viewing. This is a wallet perfect for water play, snow play, and other activities. The opening has a high level of water resistance, closing with a zipper, then rolling up the fabric and securing it with Velcro. It has loop holes for attaching straps, and is sized to hold a smartphone or car keys. Material: 420-denier nylon Weight: 29g Size: 12 x 19cm Used about twice, at the beach. I will offer a small discount if you purchase it with other items. Thank you.
