Doodles are the original Dry-erasable skateboard longboard wheels. You get to design your wheels before you ride.
These wheels have a special print on the surface to be colored before you ever get it on the ground. Once you color those, you have the face of the wheel to decorate.
The wheels come with dry-erasable markers to decorate your wheels.
Dry erase marker are removable from the surface of the wheels, pre-ridden. Permanent markers will not erase, but stain the wheels... this can be a neat effect, but use with caution, as this is permanent.
