The winter cold is still going on. Even if you wear thick clothes and carry a warmer, your hands and feet tend to get sick. I have found a product that addresses such concerns, so I would like to introduce it.
First of all, "For rolled poka wrists" (Kiribai Chemical). A set of 2 holders to wrap around your wrist and 4 special heating sheets. All you have to do is put the heat sheet in the holder pocket and then wrap it around your wrist. The heating sheet immediately begins to heat up, and as soon as you see it, it warms up to your fingertips. It will be useful not only when you go out in the open air, but also in the kitchen or workplace in the morning when the heating is not working yet! Ankle products are also available as sister products.
Next is "Mysterious feet that don't get cold and toes from above Cairo" that Kiri Ash Chemical also develops. By sticking it on the socks, it warms from the toes to the ankles. Because it is thin, you can wear shoes as it is, and it can also be used for pantyhose. There are two types, one is attached to the instep and the other is attached to the sole of the foot.
It's a winter time when going out is a hassle and you don't want to move much in your house. If you warm your limbs with such goods, you may be able to become active even in the morning and evening when it tends to get cold. How about using it in addition to the usual Cairo? The author purchased the above two products from Amazon.co.jp. "For rolled poka wrists" (2 holders + 4 sheets) was 778 yen, and "Mysterious feet that keep your feet warm and toes from above" (for 5 pairs) was 280 yen.
