Which meluna is it Heaven? Soft or their traditional one? I have the soft and i find i have to fold it in 3 - like an S. It doesn't pop open like that inside - i can tell, because it comes out mishapen, like an oval.
I think the Soft is a bit harder to get the hang of because it is so soft. The other ones pop open easier.

Can't help MadB. You can get one with glitter, just for special occasions.
