The Invisi Seamless Brief is our first cotton seamless bikini cut period underwear brief.  Undetectable under your tight-fitting clothing, leaving no trace of panty line as the seams are bonded and flat lying so as not to dig in.  Suitable for moderate days and flows, holding a maximum of 30 ml. Lining goes up halfway up front and back of the underwear.

Currently available in nude/ beige, cinnamon, garnet, plum and black. No PFAS.
