Recently I placed an order and the seller stated she would provide these with my order: 2 Logos Included Include Source File Logo Transparency Printable Resolution File Include 3D Mockup Include Stationery Designs Include Social Media Kit Vector File unlimited Revisions Can someone explain what a social media kit is? Can someone explain the difference between a vector file and source file? What does 3D mockup and logo transparency mean? Any help is appreciated. Thanks.
