It would be a weird of people to think that they won a 1000$ prize or an endless supply of soft drinks because of a random graphic designer, but in a lot of situations, that is exactly the case. And this particular scenario can be easily explained with these new PSD mockups shared by Free PSD Templates.
Coming in 4000 x 3200 pixels resolution at 300 dpi (RGB), the mockups display 2 metal bottle caps that you can use to display your top and bottom (inner surface) designs. These designs can include logos, labels, prize designs, icons, and other creative graphics which can be added to the mockups via Photoshop. All you have to do here is choose the designs you’d like to include, drag and drop them unto the smart object layers, and see them instantly appear unto the surfaces of the caps with no need for further editing.
