Miếng Dán Giữ Ấm Kobuko 10 miếng 1 phần

Miếng dán giữ nhiệt tôi bắt đầu xài từ khi ở VN, qua đây vào mùa lạnh càng xài nhiều. Loại này rất tốt, nóng lâu hơn mình nghĩ. Dùng rất sướng

I love this product. The heat is not burning hot, but very warm, consistent and lasts long. It's great for cramps and muscle pain.

I purchased at least 25 packages of this Kokubo Instawarm from Weee for my family and friends since I heard about them. I leave at least one package (of 10 pads) in my car during the cold months just in case. We had been through a cold winter without electricity and heater for almost 3 days and the temperature inside my house during those days was in the low 30's. I wish if I knew about this Instanwarm back then 😭😭.

My sister recommended this to me. I tried this in lieu of a reusable heat pack and it works great as a substitute. I can't tell you if it actually lasts 12 hours as it claims on the pack, because I haven't used one for that long, but it stays warm longer than the reusable ones for sure. The heat it emits is just right and consistent for my use. Highly recommended.

Has helped a lot with cramps. Was surprised that it was still hot after waking up.

The size is not too big or too small, good for putting on the stomach or back. I use body warmers all year round, so I am glad there are so many in the package.
