Insta-Heat Reuseable Hand Warmers

Work great. But for us, the need to boil these after every use made then incredibly inconvenient and disposable

As opposed to the single use chemical ones?

These are phenomenal !
Perfect to get your hands warm in a hurry !
The fact you can boil them to reset them for another use is an added bonus, plus…when ya boil them…ya know they’re sterilized for the next use !
My mom’s hands are always cold in the winter…I put one in each hand under her thumb holed long sleeved shirt…Voila…she’s a happy camper !

How many re-uses can you get out of one?

I doubt that info is available. It’ll depend on care and use. I would imagine quite a few though.
