This case is made of water-resistant, flexible, and tough vinyl rubber (PVC). It's perfect for protecting valuables in outdoor and leisure activities near water, such as camping, fishing, swimming, and surfing. It can also be used in everyday situations, like a keychain, to hold cash and small items. *Approximate storage size: about 10 bills, about 40 coins, or about 5-6 cigarettes. Total length: approx. 105mm x Φ35mm / Inner diameter: 85 x 25mm (slightly expandable) I bought this but never used it, so it's been stored at home. I'm selling it to organize my belongings. 【Search terms】 LOG INAVANCE / INAVANCE NATALDESIGN / NATAL DESIGN oldmountain / Old Mountain The Arth / The Arth neru design works / Neru Design Works GRINDLODGE / Grind Lodge Grind Lodger Asimocrafts / Asimocrafts Ballistics / Ballistics a&f / A&F device works / Device Works Coleman / Coleman Snow Peak / Snow Peak Nordisk / Nordisk msr / MSR Goal Zero Minimal Works Kermit Chair goalzero / Goal Zero Nordisk The North Face Hilleberg 38explore
