It's a really similar shape to L lunette but slightly smaller in all dimensions and really soft. I'm not having any trouble getting it to open because the rim is comparatively firm. I've tried the large fleur before and I didn't like it as much because of the shape. So if you like the large lunette but need something softer, I think cuplee is a better fit than fleur.
My only concern is that it seems there are small "micro tears" in the inside of the cup if I look very close. I don't know if they were there before I wore it so I'm not sure if they are left over from the molding process or developing stress marks. Do any cuplee users have these inside the cup?
