I had an ugly gray rectangular version of this as a child. This is much swankier.

Measuring in at 4” across the widest part and 3.5” long this palm sized heat pack is great for some on the go snuggly warmth. It's a durable PVC heart filled with a gel and a metal activator disc inside that when the disc is flexed causes the gel to crystalize and release heat. It's re-usable, it must be boiled to re-charge, but it shouldn't touch metal in the process. I find the best method is to fill a small saucepan with water and put a face cloth in with the heartwarmer on top. Let the water boil till all the crystals liquify and then either fish it out with a plastic spoon or wait for the water to completely cool. It's compatible with all lubrication types, oil, water-based, or silicone.

It can be cleaned easily with soap and water or toy cleaner after use, and since it has to be boiled to re-charge it's relatively sanitary. I wouldn't recommend running this through the dishwasher since it won't re-charge it and you may have one of those super charged machine that actually gets the water to a ridiculously high temperature and may make the PVC melt.

This product, according to my husband is “the best damn thing you've ever gotten from Eden Fantasys!” We found the warmth to comforting and a definite aid to working out the ginormous demonic muscle knots that are a plague to us both. When the gel first solidifies it's hard as a rock but this is softened with a little kneading of the pack. It doesn't glide over the skin easily on its own so I recommend using a little massage oil or gel, or your favorite lubricant. It also works great with the oil from massage candles, once you've worked it in a little grab the heartwarmer and it seems to extend the life of the massage oil a little. I've used it in the tub (hey! it floats!) to no ill effect so it's waterproof but I think that was a given.

I can wholeheartedly recommend this to pretty much everyone. I've used it to ease menstrual cramps, or a stiff neck, even to warm up our bed one particularly cold night. It's perfect for a sensual encounter or some tender time, 'cause lets face it, it can't always be crazy triple jointed monkey sex. The only thing about the heartwarmer I dislike is its initial hardness and the pain in the ass of boiling it to re-charge it, otherwise it's a joy.

still one of our most used items, great for a nice massage or a sore muscle! One nice trick we learned if you run the heart-warmer over your back a few times, followed by a massage bar it softens much faster and makes for great massage.
