I think I'll have the opportunity to try it out very soon and I'll write a review then.
The cup with the bag it came with.
Blue on left is large Lunette, SuperJennie in the middle, Large Fleur on the right.
Showing how the rims are the same diameter, but shaped slightly differently.
They seem to squish the same amount.
The large Lunette fits inside!
So does the (bare) large Fleur.
It has stars between the grip rings if you are into decorations.
