Reusable Geometric Hand Warmer [2025 Model]

This is a reusable hand warmer. It heats up in just 10 seconds after being switched on and lasts for up to 5 hours. Since it's rechargeable, it can be used repeatedly, making it economical. The warmth can be adjusted to two levels: high (approx. 50℃) and low (approx. 45℃). It can be charged by connecting the included USB cord to an AC adapter or computer, and it can also be used as a mobile battery. (Starting with the 2025 model, the charging cord has been changed to Type-C to C.) A 6-hour auto-off function has been added, so you don't have to worry if you forget to turn it off. It comes in a wide variety of colors and features the Francfranc logo as an accent. The cute, round oval body fits comfortably in your hand and is extremely practical. Designed with only the essential functions, a charging connector and power switch, on the bottom of the main unit, it's easy for anyone to use, even those who are not good with gadgets. It comes with a drawstring storage bag for convenient portability. Not only does it prevent scratches on the main unit in your bag or pocket, but it can also be used as a cover when you want to reduce heat while it's operating. Its palm-sized design is perfect for daily use during commutes to school or work. If you put the strap around your wrist, you can be sure it won't slip from your hand while walking or standing up from a seat on a train or bus.Source: https://francfranc.com/
