Here is a photo so you can see the size differences. I am really glad I decided to order the medium and not the small. The medium already looks so little to me!
Large Klassik MeLuna, Small Divacup, Medium Soft MeLuna
I have had the diva about 8 months and it works wonderfully for me. When I saw the glitter Meluna I couldn't resist. I just had my period so I will have to wait a month to see how the MeLuna cups work for me.
