【Background】 When mountaineering, using mountain hut and trailhead toilets is unavoidable. In many cases, a "100-yen coin" is required, but taking your wallet out of your backpack or removing rain gear can be surprisingly troublesome. Therefore, we created a "100-yen coin-only case" for toilets. The naming is a chuckle-inducing "UnCoin DCF." It's a silly name, but we've seriously considered and carefully crafted it. This is mountaineering gear that allows you to carry "coins to use in the toilet" without forgetting. Even after descending the mountain and replacing the cash and cards in your wallet, please keep this pouch and the 100-yen coins as mountain gear. 【Features】 ● A lightweight DCF case to combat the surprisingly bulky weight of 100-yen coins, a major enemy of UL (Ultralight) mountaineering. ● An item exclusively for mountaineers, ready to use "when you need it." ● Includes a soft, glow-in-the-dark TPU inner case, also used for smartphone cases. It can hold up to 18 coins, separated into groups of 3. This is equivalent to 1,800 yen, enough for a 4-night mid-range traverse. ● The design allows for a small gap inside even with the inner case inserted. Removing the inner case allows it to be used as a regular coin case for 500-yen coins, but we recommend using it exclusively for 100-yen coins. ● Comes with a removable plastic carabiner. 【Specs】 ・Size: Approximately 26mm (H) x 50mm (W) x 26mm (D) ・Weight: Approximately 8.5g (including TPU inner case approx. 3.8g, carabiner approx. 0.7g) ・Materials: DCF 1.43oz (Dyneema Composite Fabric) + TPU 【Notes】 ・Decorative items other than the title are not included. ・Please refrain from price negotiations. ・Will be shipped in simple packaging.
