The belly pinches, the mood shifts, no motivation, mixed feelings... we say it like it is: PMS is a pain in the neck. For official members of the PMS CLUB, the following recommendation applies: hot water bottle, cozy blanket, hot chocolate... with whipped cream, of course! Our cozy hot water bottle keeps you nice and warm. It is extra large and has a flat opening, so you can easily place it on your lower back. Our hot water bottles are made of natural rubber. The material naturally has a typical odor that dissipates after a short time.
