This is a simple, handmade coin case for UL hikers. While designed as a coin case, it might also work as a minimalist wallet, as cards can fit in it with a tight squeeze. Bills can be folded in thirds to fit. It could also be used to hold wireless earbuds or as a pill case for carrying medication. This item is being offered at this price as a prototype. Perfect for hiking or a quick outing. * Seam sealing is not applied. * Due to the nature of DCF fabric, there may be wrinkles on the surface. Fabric: 1.0 oz Dyneema® Composite Fabric Zipper: Water-resistant zipper YKK® Aquaguard (Green) Weight: Approximately 3g This item uses the same fabric and parts as major outdoor brands, so the durability and quality should be comparable. However, this is a handmade item by an amateur. While I strive for careful sewing, please refrain from purchasing if you are looking for professional techniques or the quality of a mass-produced product.
