rae is a new kind of period heat device, developed by Scarlet’s Jo, who was tired of her endo struggle. She needed a reusable, portable, and longer-lasting solution to the wheat bags, sticky patches, and hot water bottles of the world.

Made from high-grade, hypoallergenic silicone and certified by RoHS, RCM, and IP54, rae has been through rigorous testing to make sure it’s safe — with auto-shut off and overheat protection, there’s no worries. Just warmth. 

Heating up in 5 minutes, rae reaches a comfy 50°c. That’s hot. Just press a button for 3 seconds to turn on, toggle between three heat settings: low (5 hours), medium (3 hours), or high (2 hours), and feel the heat.

rae loves a road trip or coffee date. Slip it in our custom Period Pocket Underwear when on the run for hands-free heat, then keep it in its case when not in use. Oh, and if traveling with rae in your carry-on, check airline guidelines for lithium batteries.
