Product Details
This item will be shipped in simple packaging via Nekoposu (a contactless delivery service). Thank you for looking.
This is a genuine Hakkin Kairo fuel cup. It was kept as a spare but is now being listed due to decluttering. Please check the photos for details such as the internal memory condition, engraving (PAT. 716102), and measured weight (4.2g). It is fully functional.
[Reason for Listing]
I used two Hakkin Kairo units as a heat source when riding my motorcycle on the highway during winter nights.
In the winter around the Kanto region, grip heaters are usually sufficient. However, highway riding on nights close to freezing temperatures is a different story. By equipping two Hakkin Kairo units that stably generate heat for 12 hours without maintenance, I was able to endure harsh conditions.
Incidentally, while riding on the highway at 2°C, my body was warm but my arms were intensely cold. I discovered my own secret strategy: using Montbell kids' leg warmers on my arms. If you wear a nice rain coat over it, no one will know about the modifications inside. I'm not sure if it's recommendable for everyone, but I got through the winter this way.
When I purchased them as a set of two, one was kept as a spare with hardly any use, so I am releasing it now due to decluttering. This unit has survived (?), so you can use it with confidence.
