Our HotHands® family of air activated warmers all contain a mixture of natural ingredients that when exposed to air react together to produce heat. This is accomplished through an extremely fast oxidation process. Ingredients include: iron powder, water, salt, activated charcoal and vermiculite. HotHands® has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100°F to 180°F for duration of 1 to 20+ hours.

HotHands® warmers are made of natural ingredients and safe for the environment. Just use and dispose of in your everyday garbage.

Although the need is always great, donation requests for Kobayashi products have been especially high recently. While we try to help as many as we can, we are unable to fulfill any donation requests at this time.

If you purchased one of our products through an online retailer (and not directly from Kobayashi), please contact that retailer for any issues or questions related to the order. They will have your order information and will be able to assist you.

We are currently unable to fulfill any donation requests. We thank you for your understanding.

In lieu of donations and sponsorships, Kobayashi actively supports several outdoor organizations with the mission of sustaining and promoting outdoor recreation. By focusing our support with these groups, we are working to make the most of our resources to the benefit of all customers. Therefore, we are unable to provide in-kind product donations or local sponsorships.

At times, individuals may express a desire to submit suggestions, requests for new products, technology, designs, manufacturing methods, etc. to Kobayashi. However, we are regularly conducting independent research in various fields, and there is a chance that ideas, new products, technologies, designs, manufacturing methods, etc. may not yet be publicly announced but independently developed by us that may resemble those submitted by the individual. In order to avoid any misunderstandings, and as a general principle, Kobayashi does not accept such proposals.

HotHands® is manufactured by Kobayashi Healthcare International, Inc., innovators in providing cutting-edge solutions to every-day needs.
