When traveling in colder climates, having a reliable source of warmth can make all the difference. During a recent trip, we tried the Kiribai Kairo non-stick hand warmers from Japan—and they outperformed every other brand we had packed.


As Singaporeans, we are used to warm weather all year round, so sudden exposure to cold temperatures can be quite uncomfortable. This heat pack kept us toasty and warm throughout the day. It was small enough to fit snugly in our jacket pockets or be held directly in our hands, making it a convenient companion during chilly walks or long outdoor waits.


While most heat packs tend to last only 8 to 12 hours before fizzling out, this one delivered consistent warmth for a full 24 hours.

We also found it helpful not just for cold hands, but for easing menstrual cramps when placed near the abdomen—without needing to stick it on. The non-adhesive design meant we could easily shift it around as needed.


The Kiribai Kairo warmers begin heating up immediately once opened, reaching an average temperature of 51°C, with a maximum of 65°C. Compact and convenient at 13cm by 9.5cm, this Japanese heat pack is ideal for travel, winter adventures, or simply staying cozy indoors.


This is not a sponsored post—just a glowing review from personal experience. For anyone preparing for a trip to a colder destination, these little heat packs might just be your next travel essential!
