Sock heaters size S/M - box - 10 pcs

GRZEJKI heating inserts are an effective heat source for outdoor activities in freezing conditions. They start working immediately after removal from the packaging and provide thermal comfort for many hours. These body warmers allow you to enjoy the outdoors even on the coldest days.

The warmers operate based on an iron oxidation reaction—heat is released steadily and consistently over a long period. This simple principle of operation makes GRZEJKI exceptionally reliable. Once used, the warmers can be safely disposed of in regular household waste, as the contents are non-toxic and non-flammable.

Instructions for use: Remove the sachet from the plastic film and shake it. The warmer activates upon contact with air and will begin to emit pleasant heat shortly after.

Safety Use only as intended. Prolonged contact with the skin, especially in cases of poor blood circulation, may cause low-temperature burns. If you notice symptoms such as redness, itching, or a burning sensation, stop using the warmer immediately. Exercise extreme caution when using the warmers on children or persons with limited mobility and/or sensory perception. Do not use while sleeping.

For children under 3 years of age, there is a risk of choking on fragments of the plastic packaging—the warmers are not toys.
