The menstrual heating patch provides soothing warmth during menstruation for up to 12 hours. The filling of the patch contains no active substances and heats up by itself within a few minutes on contact with oxygen after opening the plastic bag. Thanks to the harmless glue and pleasant heat release, it can be applied directly to the skin or, alternatively, to the inside of pants. One pack contains two individually wrapped heating patches. Ingredients: Iron, water, diatomaceous earth, activated charcoal, sodium chloride.
