You mentioned that you could “Sprinkle the contents in your garden”. What will this do for my rose garden and what is the contents made of? Thank for your help and i love using your product. (Toni)

Hi Toni! Thanks for using Hotteeze! Hotteeze is mainly iron filings and the soil conditioner is pottasium chloride…I honestly don’t know if it’ll help the roses but it won’t harm them!

How does a Hotteeze work?

Each Hotteeze heat pad contains iron powder, water, vermiculite, carbon and salt. When you open a Hotteeze, the iron oxidizes with the air, creating heat. If you accidentally open it up, quickly seal it in a plastic bag to stop the oxidization process.

Why should I not use your pads if I am diabetic?

The directions recommend you check with your doctor before using them because some diabetics have no sensation in their extremities and wouldn’t be able to judge whether the Hotteeze heat pad or foot pad was getting too hot. Thus they could end up burning themselves without feeling it.

Why can’t I wear it directly on my skin?

You might burn yourself. Hotteeze will feel cozy at first, but after a while it will heat right up without you noticing and might feel too hot. You will probably start to sweat too, in which case the pad will slip off and you won’t get your 12 hours of guaranteed heat.

Why shouldn’t I wear it to bed?

If you fall asleep wearing a Hotteeze, you cannot properly monitor your comfort level. The heat might sneak up on you and cause a burn.

Are they bad for the environment?

Hotteeze contain natural ingredients which are biodegradable, so when they’re done, you can throw them away guilt-free! The contents can be reused as a soil conditioner, which contributes to the reduction of wastes. The outer packet is combustible and does not generate toxic gases.

Where do they come from?

Hotteeze were invented by the Japanese and are manufactured in Japan. Your Japanese friends will know them as KAIRO. They are very popular in Japan and are recommended for various remedies. For example, if you catch a cold, a Japanese person will recommend that you stick a Hotteeze over your abdomen to help you recover more quickly.

What if I’m pregnant?

Whatever you do, NEVER put a Hotteeze near your abdomen, and check with your doctor before using it on any other part of your body.

What if Hotteeze gets wet?

If you get a Hotteeze wet, you can kiss it goodbye! The water will stop the oxidization process.

What if my pet eats it?

If swallowed, rinse the mouth with water and seek medical advice.

Are hotteeze safe to travel with, for example do they set off alarms, get picked up on x-ray machines, expire in the plane?

No they are completely safe and will not set off any alarms.

Are they reusable?

No. Once the 12 hours of heat is finished, that’s it! BUT – You can use the Hotteeze for half the time, pop it in an airtight bag to stop the oxidization process, and then keep using the rest of the hours of heat the next day.

Can I use Hotteeze on my knee/elbow/shin/leg and other body parts?

Yes, but only through clothes. We recommend using a cloth flexible tube bandage that you can double over.

Can I sleep with them on?

No, NEVER! You can get a low-temperature burn
