Self-made by a former backpacker｜10,000 Yen Bill Holder & Emergency Cash Capsule (3D Printed) 【Product Features】 This cylindrical case was born from my experience as a backpacker, designed to carry 10,000 yen bills in the smallest and lightest way possible. I designed it with a focus on ensuring that banknotes wouldn't be folded, wouldn't take up much space, and would close securely, even while traveling. The fit between the lid and the body was repeatedly tested from a clearance-free design, and finely adjusted to achieve an appropriate holding force. After printing, the plastic burrs are removed one by one with a cutter knife. Therefore, it is not a completely mass-produced product, and there is a slight handmade feel, but each one is checked for its condition. When new, the lid may feel a little stiff to open and close for the first few times (about 5 times), but the fit will become familiar with use, and the feel will become natural. A simple Chinese numeral "一" (one) is engraved on the bottom. ■ Ultra-lightweight & Compact Weight: Approximately 8g, Diameter: Approximately 1.5cm, Length: Approximately 8cm. For minimalists who want to reduce their luggage to the extreme, runners, mountaineers, and overseas travelers. It's a dedicated design for carrying 10,000 yen bills in the "smallest and lightest" way. ■ About the Original Design This product is an original model that I designed from scratch. Unlike products that simply imitate the shape, I have also tested the internal clearance design and durability. 【Future Lineup Plans】 Currently, in addition to this model (for 10,000 yen bills), we are developing the following series in response to requests. ・30,000 yen storage model (under development) ・50,000 yen storage model (under development) We plan to release them sequentially, so please follow us and wait. 【Product Details】 ・Material: High-quality PLA (environmentally friendly plant-based plastic) ・Size: Approximately 1.5cm in diameter × Approximately 8cm in length ・Color: Matte Black (see photo) ・Quantity: 1 piece (*Bills are not included) ・There are layer lines (fine streaks) unique to 3D printers, but there is no problem with practical strength. ・Due to the characteristics of PLA material, it may deform if left in high temperatures (such as inside a car in summer) above 60 degrees Celsius. This product is made to order after receiving your order. We try to respond as quickly as possible, but please understand that it may take some time for production and finishing.
