In this Illustrator Toolbox we have an extensive selection of UI templates, all in AI and EPS format, and all perfect if you are a web, mobile or app designer that prefers to use Adobe Illustrator rather than the more commonly used Photoshop.

So, if you are a UI designer who does prefer Illustrator over everything else, then you may consider this post as your treasure chest.
