This is a 30-pack of Kamoto's powerful warming hand warmer, "Oniatsu" (Demon Heat). Although the sunlight in March has become spring-like, it's still freezing cold in the mornings and evenings, or on windy days. Especially with April approaching, it's cherry blossom season! When viewing night cherry blossoms, picnicking, or attending outdoor events, the cold seeps in from your feet. This "Oniatsu" is an outdoor-only type boasting a higher maximum temperature of 70°C (average 56°C) than regular hand warmers. On spring nights when you want to go out in lighter clothing, just slip it under your coat, and you can enjoy events until the end without worrying about the cold. We are selling them at a low price as stock is limited. Please stock up for upcoming leisure activities and to combat temperature fluctuations!
