Driven by the spring creative force DryIcons' Team designed and developed another free icon set, which we called "Blossom". Standing out with unique design, our new free icons are little works of art. We used only two colors: black and white and managed to produce one very stylish, 3D looking, modern, but most of all- unique, icon set. The back of the icon is made of swirly leaves and flowers, reminding us of blossoming trees and flowers. Get creative with these free icons and enjoy the spring blossom. This free icon set contains 51 high quality, free icons in these sizes: 16x16px, 32x32px, 48x48px, 64x64px and 128x128px and 32-bit transparency PNG file format.
