Mock-Ups.
A mockup is a full-size model of a design or device, used for product presentations or other purposes.
Think of it as a means of showing off what your design will actually look like when it's put out into the real world. You can see lots of mockup examples in our blog post on the latest mockup trends for 2020.
Depending on your skills and time, you can go through the process of creating your own mockup using dedicated graphics software such as Adobe Illustrator or Photoshop, but sometimes you might be better off using more basic tools like the Mockup Generators offered at Placeit.
