Choosing the size

What is the best size for you?
 
The best choice for a young girl not yet gave birth is a small (S) menstrual cup.
Diameter is 40 mm, height is 47 is. The steam is 21 mm. Volume is 20 ml. To holes 16ml.
 
If you are over 25 years old or you are already a mother, you better use large (L) menstrual cup.
Diameter is 44 mm, height is 53 is. The steam is 17 mm. Volume is 30 ml. To holes 25ml.
 
The size of a handle (17/21 mm) can be shortened to choose the optimal one. You can remove it at all, but you should be careful not to damage the menstrual cup itself or break its airtightness.
