The Heart Warmer by pipedream is an item which heats up via chemical reaction. This product has so many uses, but the ones I prefer it for are keeping my hands warm when they are cold, putting it on my tummy when I have cramps, and having my boyfriend use it on my back for massage!

This item is made out of PVC which is a thick material which allows the warmth to stay trapped longer. It smells an awful lot like a pool raft, but doesn't have any taste to it at all. The pool raft scent went away after the first time I "reactivated" it by boiling it. PVC is safe to use with water or silicone based lubes and makes it a lot more durable as well. When you haven't used it yet and there are no crystals inside you can see around disc on the inside, which is made out of iron. To use the warmer, you just click the disc inside. Don't worry, the disc won't break so just hold the sides and press the center! Immediately you will notice the color changing on the inside. It will be a milky color as the crystals form, and it spreads pretty fast! The crystals are a little hard, and as it begins to cool the warmer hardens a lot more! Once you boil it, this reverses the crystallization and it goes back to normal! For the full science of the product you can check out this review.

To reactivate, you want to put a towel or washcloth on the bottom of a pan and place the warmer on the towel, boiling for about 10 minutes or until the crystals are totally dissolved. To take it out I'd recommend using a pair of tongs so it doesn't burst and so you don't burn yourself. Set the warmer down on a dry towel to cool off. Be careful because in this state, the hot PVC will be less sturdy and more likely to burst!

The warmth in the warmer lasts anywhere from 30 minutes to an hour depending on the room temperature. Though this shouldn't really get dirty you can always rinse it off with water and soap, if the boiling isn't enough for you! But boiling it sterilizes, so this thing can get super clean!

The box that the product comes in is white and cardboard-feeling. It isn't much bigger than the product itself, so I like to use that for storage to keep it safe from cat claws! The box has a picture of the product as well as company info and how to use and reuse the item!

I've used my sister's Heart Warmer and finally decided maybe I should just get my own! It works so well and the heart shape makes it great! I love this item, and I really want to get more!
