SWITCHEROO COLOUR CHANGING WASHABLE MARKER PENS
Set of 12 colour changing washable marker pens by Ooly. Each marker has two sides, one for regular colour and the other for a mystery colour change. After you draw with the regular marker just apply the switcheroo side to see an unexpected and magical colour change. Chiseled tip for thick and thin coloured strokes. Switcheroos are also completely washable in case of any colouring accidents.
