Custom Designs Transfers Dry Transfer Decals are the fastest and easiest way to customize a derby racer. Colorful stripes, flames, numbers, and graphics apply easily in seconds without the mess and bother of wet process decals. They are high quality rub on decals that can be rubbed around contours and over textures, unlike stick on decals. With Dry Transfer Decals there is no clear film around the edges of decals, as occurs with wet process and stick on decals.
