Big Hug Self-Heating Patches are Popmask's solution to period pain that doesn't involve bulky heating pads or pills.

These single-use patches activate when exposed to air, warming up within 30 seconds to provide soothing heat that lasts up to 12 hours. You stick them to the outside of your underwear or clothing (not directly on skin), positioning them over your lower abdomen or lower back wherever cramps hit hardest.

The patches are biodegradable, ultra-thin, and discreet enough to wear under clothing. They use natural ingredients like iron powder and activated carbon to generate heat. The heat helps relax cramping muscles and provides drug-free pain relief.
