If you put this on the inside of the box, a special ink must be used. I’ve always thought an ad or logo inside a box would be great though. On a similar note, of those that use custom boxes, do any of you print a logo on the bottom of the box? That way no matter which side is showing sticking out of the garbage can, your logo can be seen.As I was giving way to a chocolate craving today I looked inside the wrapper and noticed some writing. It said " This is not an empty wrapper it is a reminder to get more". I could see this working for a pizza box. What do you think?
