【Production Background】 When climbing mountains, using mountain huts and trailhead toilets is unavoidable. In most cases, a "100-yen coin" is required, but it's surprisingly troublesome to take out your wallet from your backpack or remove your rain gear. Therefore, we created a "100-yen coin dedicated case" for toilet use. The name is a chuckle-worthy "UnCoin DCF." Despite the silly name, it is made with serious thought and care. It's a piece of mountaineering gear that helps you remember to carry the "coin for toilet use." Even after you change your wallet's cash and cards after descending, please store this pouch and the 100-yen coin as mountain equipment. 【Features】 ● The weight of 100-yen coins, which is a nuisance for UL (Ultra Lightweight) mountaineering, adds up. The case itself is made of lightweight DCF. ● A dedicated item for mountaineers that can be quickly used in "that" moment. ● It has a soft, glow-in-the-dark TPU inner material, also used in smartphone cases. It can store up to 18 coins, divided into groups of three 100-yen coins. This is intended for medium-length treks of about 4 nights, holding 1,800 yen. ● There is a slight gap inside even with the inner case. If you remove the inner case, it can be used as a regular coin case that fits 500-yen coins, but we prefer you use it exclusively for 100-yen coins. ● Comes with a detachable plastic carabiner. 【Specifications】 ・Size: Approx. 26mm (height) x 50mm (width) x 26mm (depth) ・Weight: Approx. 8.5g (including TPU inner approx. 3.8g and carabiner approx. 0.7g) ・Material: DCF 1.43oz (Dyneema Composite Fabric) + TPU 【Notes】 ● Accessories other than the title are not included. ● Please refrain from price negotiations. ● Ships in simple packaging.
