Here’s a mockup of a cardboard pizza box available in five PSD files. I took a slightly different approach with this mockup since the box starts off as white. In the preview files, you can easily change the “cardboard” color using Photoshop. The best part? If you want to switch to a different color for the box, it only takes a few moments. No matter if you choose white, black, or any other shade, your design will always come out looking great and realistic.
