At certain times, professionality is key for a successful job, especially one that demands a refined look that projects sophistication and classiness. Luckily, we decided to share with you this letter paper mockup from Zippy Pixels.
The freebie offers a clean 2D US letter in 300 DPI. In order to edit the PSD mockup, you need to have a CS4+ Adobe Photoshop version using the smart object layers that enable you to personalize it. With a couple of clicks, you can easily download the free 600 x 394 pixels version that can only be used for personal use. However, you can also get your hands on the 3500 x 2300 pixels mockup that includes 7 additional mockups as a bonus that showcase the letter paper from various angles (both folded and unfolded). This version can be used for both commercial and personal purposes.
