If you're still struggling to buy stickers to make your phone special, check out the UNIK, a Nokia concept phone from French designer Clement Logereau. Part Lego, part jigsaw puzzle, you can arrange the 152 squares that make up the back of the phone. Design a personal phone shell pattern. Students who love to play with color will certainly love it, but be careful not to get rid of a certain piece, otherwise it can be troublesome ~
