This is the simplest product I've ever seen that is actually vaporware. This product doesn't exist at all and they've simply digitally mocked-up some examples. It can't be purchased, and it's not being produced. Good job on that physical vaporware stuff!
I really like this wrapping paper and would like to see more wrapping paper that imitates other objects in this fashion.
I assume it'd be significantly more expensive than normal wrapping paper because it's suited to particular form factors of the presents, but as a business idea, I could see a larger service that matches these sorts of wrapping papers to products that would work with them.
