The Duchess reusable menstrual cup is similar to other menstrual cups in shape and material (medical grade silicone) but comes in a variety of fun colors including pink, purple, blue, red, and clear. The cup has a familiar ridge along the top and then a smooth, ridgeless stem that may be more comfortable for some women but may also make the cup more slippery and difficult to remove. Some users also had trouble getting it to pop open (though many find that it pops open easier with practice).
One of the main benefits of the Duchess Cup over other cups is that it's available as a two-pack, meaning that you get two cups for the same price as one of another cup. That means you can leave one in your purse for emergencies and one at home.
