The Untwist v1 comes with a custom Decal Sticker Sheet with 4 amazing Holographic Dots.  The Dots can be placed anywhere... but we suggest placing them somewhere on the wheel.  This creates a neat visual effect as the wheel spins!  (Note: the dots are not removable and, once in place, cannot be relocated.)

In addition, Paint Pens and Paint Markers work nicely on the Anodized Aluminum.  The Wheel can be a canvas, and any design is possible!
