Reusable Heat Packs, Set of 8 - Gel Hand Warmer with Snap to Heat Metal Disc Technology for One Click Heating - Instant to Go Pocket Hand Warmer with Gift Packaging.

Wonderful product, why? Because they are reusable, hundreds if not thousands of times! We love them! I have used this type of hot pack since I was a kid on a paper route 40 years ago this was my choice, buy them once, take care of them and use them all winter, no buying more and more like other products. And today I use them for working on the farm in the bitter cold winds. If you have a heat source on you for your body to draw from then you can stay warm. and these are great for that because they are instant, on demand heat.The other type where you open the pack and then shake and wiggle the little bag until it is hot which usually takes 5 minutes is not for me, we are talking about being cold...I want heat a minute ago! These packs are hot the instant you bend the little tab inside...it is perfect and great. Almost better than that is that they are reusable, just toss in a pot of water to boil (about 5 min) let them cool and use them again. Amazing. There should be 6 stars available just for this product. Thanks! I'm so glad they still make these...

Love these small hand warmers! Kids can use them easily and at the end of the day it’s easy to boil them and get them ready to be reused. I like how compact they are and the colors are fun also. My kids enjoy them.

Cheap had two leak and burn me snd they get so stiff once activated I dislike and scared too use now with the leaks

Bought these for the grandkids to get them interested in science explaining to him why these worked interesting time they worked great and regeneration by boiling flawless nice little science experiment for my grandkids

This product works great, but it was very difficult to get it back to the liquid state even when following directions. Unfortunately, I had to return it.

Love these, have always loved these. You boil them after use and it resets for future use, i keep these with me in my car just in case as I live in michigan and am a home care RN, these have saved my hands when my car broke down in a snow storm.

Only used these twice, bit exactly what I expected. Solid buy for reusable hand warmers

When I pulled these out to use them for the second ski season, I boiled them as directed, but they’re not working like expected. The first season was fine, but I was hoping to use these year after year.Now, they have air bubbles, crystals that don’t dissolve, and then they immediately heat up (rather than waiting for the button to be pushed). Unsure how long they’ll stay hot for, but I’m not risking it on the slopes.
