Smooth UI Kit (Updated with PSD download)

This includes everything you see here: buttons, on/off switches, tags, a slider, checkboxes, radio buttons, a tootip and more. Everything is entirely vector so it will be easy to scale to any size. This even includes a custom pattern of one of my backgrounds that everyone seems to like so much.
