Vernis agenda owners, i am consider getting a vernis agenda, but have some Qs i like to find some A before i purchase: Can Vernis agenda be used everyday? Is it more of eye candy than functional piece? Will the side, button closure area get 'wrinkles' from usage? Has anyone SO medium ring size agenda? I tried to SO Damier Koala in Med ring, but got turn down >"< Is Vernis agenda your one and only agenda, or you rotate between other lines of agenda? If so, what's the reason? Many thanks!
