Clean Interface Kit includes hundreds of hand-crafted interface elements that are ready to be used. The kit includes full vector components like buttons, tables, modal boxes, popovers, icons, navigation, menu, dropdowns, radio buttons, checkboxes, tooltips, sliders and much more.
Everything is included in a single Photoshop .PSD file into neatly organised groups and properly named layers.
