This is a simple, minimalist, and compact wallet handmade for UL hikers. It's sized to hold folded bills. This is a prototype, so it's offered at this price. Perfect for hiking or a quick outing. * No seam sealing. * 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 (Black) Weight: Approximately 4g It uses the same fabric and parts as major outdoor brands, so the durability and quality are comparable, but it is handmade by an amateur. I strive for careful sewing, but please refrain from purchasing if you are looking for professional techniques or the quality of a mass-produced product.
