It was given to me by many people who had never used a menstrual cup "Can I really put it in myself?" or "Won't I be able to take it out?" "Which one should I choose?" It is an original menstrual cup made in Japan that is particular about eliminating the "anxiety" that prevents the use of the menstrual cup for the first time. It was born as the "first menstrual cup" for many inexperienced people who are easy to fold and put in with a patent-pending original design "Easy Line", and are less likely to feel pain by automatically closing it when taking it out. We decided on the form and size through a prototype monitor by people who have never used a menstrual cup or who have been frustrated in the past. Don't worry about which one to choose, it's easy for anyone to use, and it's a slender and long size. See below for usage instructions and frequently asked questions https://murmo.jp/pages/how-to
