![ハクキンカイロ ハクキンウォーマー スタンダード 1個入 【保温約24時間】[3個セット]](https://m.media-amazon.com/images/S/aplus-media/sota/eae5fa02-7107-41cf-a71a-05d1f5c2244f._CR0,0,150,300_PT0_SX150__.jpg)
I first learned of this product in a NHK documentary years ago, I never thought of if much more than a novelty thing specially when I moved to Japan and couldn't find it in any sort of store. It was those kind of things that felt silly as I never saw the need nor anyone using it.
Well it is my third winter in Japan and this one is quite cold, my job requires me to stay in an outdoors area for a long time and even after investing on proper Japanese modern winter clothing I still felt the cold and the need for something warm.
I don't particularly liked the idea of the disposable warmers, too much needless waste and their one use only function didn't appeal to me. So I decided to buy this one, a higher initial cost that will pay itself with years of use.
Originally I wanted the mini, but when I went to buy it they had no more of those in stock, so I changed for the standard one.
I normally give it around 15 ml of fuel, or half of the cup worth, and it works for around 10 to 12 hours inside its pouch. It made sense since the instructions told that for 24 hours you add 2 full cups, so only 1 quarter of the amount would be 8 or so hours.
On my first day using it I was honestly surprised by how long it worked. Around 8 hours of use that I thought that maybe it was starting to cool down or only giving out residual heat from the warmer and not of the fuel burning. Yet when came home and set it down on my desk and left it alone, later I picked it up to store it and saw it still running quite hot, it was 3 hours since I left it there.
My issue with the product when I opened it, is that I thought that it came with a string or lanyard to hang it around the neck, it was a misunderstanding on my side and no fault of the product.
What really bothers me is that I couldn't find it or any other version of it outside Amazon, no store near me carries it, and the prices are rising quite fast. When I first saw the mini it was 3,000 or so, the week later it was over, the standard was 3,600 or close, the week after it was 4.300, then the next week it is 6,800 apiece. It is a huge price increase in such a short amount of time.
Still the product works really well and I felt the need for more units so I purchased 2 more units, as the first one I heat my core by hanging it around my neck, the new units will be for my waist and hands, specially my hands as some nights at work they get very cold and getting the warmer from under my jacket and uniform is too much trouble and let all the heat escape.
The product is great, will and did recommend to others.
