3COINS' Three Coins rechargeable eco hot water bottle. Due to the following issues, I will sell it at a bargain price to those who understand the situation. The cover has some stains. ● Reason for the issue: Purchased at a store (purchased in 2020), but there was a charging problem, so I had it exchanged. The exchanged product was used about twice, and a charging failure occurred again for unknown reasons. I didn't feel like exchanging it, so it's been put away. I tried charging it before listing it, but it didn't work. ● Packaging: The box itself will be wrapped in a bag (waterproof measures) and shipped so that the contents are not visible. ● Product specifications: ⚪︎ Warm for about 8 hours when used as an anklet in a futon ⚪︎ Warm for about 4 hours when used as a body warmer ⚪︎ Charging time is only 15 minutes ⚪︎ Electricity cost is about 2.5 yen per charge ⚪︎ Reusable ⚪︎ Very eco-friendly ⚪︎ The cover is made of flannel material for a luxurious feel 20260116
