Obtained as a novelty item in December 2025 at the Marine & Walk commercial facility in Yokohama, a popular tourist spot. It warms up when you repeatedly click the small metal disc inside the liquid a few times. Unlike disposable hand warmers, it can be reused by warming it in hot water. Please read the instructions on the backing card for details. Unopened, unused. A set of 3 identical items. Share them with family and friends and keep them in your pocket to combat the cold. The items will be packaged by securing all three with masking tape to cardboard. They will then be placed in a plastic bag or a brown envelope and shipped via Yu-Packet Post. #RecycleEcoKairo #Kairo (Hand Warmer) #HandWarmer #ClearColor Situation: Other
