Never ask a stranger for a tampon again! The Fun Cup gives women up to 12 hours of period protection at a time. The smaller Fun Cup Size A is great for lighter days and for women who find a smaller cup to be a more comfortable fit. The larger Fun Cup Size B is great for heavier days, women who are over 30 or women who have given vaginal birth. When you’re ready, just empty it, wash it out, put it back in, and enjoy another 12 hours of not thinking about your period. Won't cause dryness or micro-tears like tampons can and it will stay in put during swimming, dancing or anything else. Small holes around the cup's rim help create a reliable seal to keep it in place. Fun Cups come with an antimicrobial Tyvek bag that is discreet, gender-neutral and small enough for a purse or glove compartment. Who should pick the Explore Kit? People who don't know what size they should choose or someone who wants one cup for heavy days and one for lighter days.
