A Japanese netizen's "mobile wallet" crafted from a modified flip phone has gone absolutely viral on Threads, proving that creativity truly knows no bounds. 
User "kiyo _1988_1227" recently shared how they pulled out this custom wallet at checkout, instantly sending the cashier into a frenzy of surprise. A closer look reveals that this "wallet" is actually an old-school flip phone, cleverly repurposed. Inside, it snugly holds an old 1,000-yen bill featuring Hideyo Noguchi, while the phone's keypad has been hollowed out to stash loose change. It's a design that's both hilarious and practical—a true "mobile wallet" in every sense!
Kiyo mentioned that the idea was actually inspired by other netizens' creations, and he encourages everyone to jump on the bandwagon. However, he also admitted that the wallet is "incredibly difficult to use," which, ironically, has the added benefit of "curbing impulse purchases."
In the comments section, someone claiming to be the original creator popped up, revealing that the modification process involves completely disassembling and reassembling the entire phone—a tedious manual task, but one that delivers immense satisfaction upon completion. Netizens flooded the comments with remarks like: "I wanna make one too!", "How much are you selling them for?", and "I've got an old phone, teach me how!"
This nostalgic and eye-catching creative wallet not only sparks fond memories of flip phones but also showcases the endless ingenuity found in everyday life.
