Looks like the shape is subtly influenced by Luv Ur Body. Capacity is about average though. Wonder how flexible they are? Googling around, looks like Lamazuna is the same company that makes Natu?!
Yeah, ahh.. I should have specified it : Lamazuna also is a -reseller- of the Natu ; but both companies are different. And Lamazuna comes from France, while Natu is Italian. Some years ago, if am not wrong, Lamazuna used to sell the MeLuna brand of cups.^^
