Grabber Hand Warmers

Simply remove the warmers from their outer packaging and expose them to the air. They will begin to warm up automatically within a few minutes.

No, these are single-use chemical warmers. Once the internal ingredients are exposed to air, the reaction cannot be paused or restarted, so it is best to use them only when you are ready for the full 10 hours of heat.

It is recommended to place the warmers inside gloves or pockets rather than directly against bare skin. If the warmers become too hot or if you have sensitive skin, keeping a layer of fabric between the pack and your skin prevents potential irritation.

Yes, they do have a shelf life. Check the packaging for the expiration date, as the chemical reaction efficiency can decrease over time if the packets are stored for several years.

While they are designed for hands, they can be placed in pockets or other areas to provide warmth. However, avoid placing them inside tight-fitting footwear or directly against your body where they might be compressed or restricted from airflow, as they require oxygen to function properly.
