All the elements contained in these icons have been carefully made in Photoshop using shapes (PSD), so that if you decide to change the size of one of them, you will still be keeping the same quality. You can basically use them for everything you need- websites, mobile interfaces, software’s, illustrations and others. It all depends on your imagination.
