Sock heaters size L/XL - box - 10 pcs

GRZEJKI heating inserts are an effective heat source that ensures thermal comfort during activities on freezing days. They start working almost immediately after being removed from the packaging, allowing you to enjoy outdoor movement regardless of the weather.

The principle of operation is based on a natural iron oxidation reaction—this ensures that heat is released steadily, consistently, and for many hours. This simple technology guarantees reliability in all conditions. After use, the warmers can be safely disposed of in general waste, as their contents are completely non-toxic and non-flammable.

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

Specifications:

• Duration: 8 hours

• Temperature: 40 – 45°C

• Dimensions: 265 x 85 mm

• Ingredients: iron powder, vermiculite, water, activated carbon, salt.

Safety Use only as intended. The warmers may cause low-temperature burns during prolonged contact with the skin, especially if blood circulation is impaired. If you observe symptoms of a low-temperature burn, such as redness, itching, or a burning sensation, discontinue use immediately. Exercise extreme caution when using the warmers on children or individuals with limited mobility and/or physical sensation. 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.
