Using every last drop of colour just got easier with the new COLOUR.WHEEL Tube Roller by COLOR.ME! This sleek, innovative tool, modeled after a skateboard wheel, is designed specifically for COLOR.ME tubes. Place the end of the tube in the slot and roll the wheel over the tube. This will push the colour towards the bottom, ensuring that you get the most out of each shade! The wheel is both compact and stylish and is both functional and attention grabbing!
