Ooh wooow !!
The Lily now exists in a compactable version - you should have a look at it hehe.
The rim is more 'conventional' than on the original cup, and this one has holes... But its concept and shape are incredible.
It also reminds me of the Meluna foldable silicone cups..
Can be worn up to 10 hours.
