I think it'd be great if Eden carried menstrual cups! Using sex toys is what motivated me to get a DivaCup in the first place; it gave me a greater understanding of material safety and some confidence about inserting it and wearing it comfortably. Plus reviews and videos on menstrual cups would be a big help for those who may never have heard of them or want personal accounts of their function and reliability.
Also the DivaCup "DivaWash" is great for washing silicone (and other) toys. It's safe, gentle, and pH balanced!
