If I purchased official licensed merchandise and resell it. Is that legal? If I pair it with homemade or other purchase items would that make a difference? For example, if I sold a mug that I made with a "Justin Beiber" T-shirt inside, Could I do that as long as I purchase the T-shirt from an official distributor? Also does anything change if the logo or name used is publically known BUT not trademarked officially?
