We have tried and tested many popular brands of washable markers on our mats, most whiteboard markers and water-based pens DO WORK. Some examples include the IKEA or CRAYOLA markers. However, for best results and the most satisfying colouring experience, we recommend that you use our Drawnby: Markers with our DrawnBy: Washable Silicone Drawing and Colouring Mats as well as the DrawnBy: Washable Silicone Coaster Mats.Our proprietary DrawnBy: Markers are developed specifically for use on silicone surfaces and are also gentle on the hands and easily washed off even when ink gets on the skin. Certain brands may not provide the same result and other washable markers tend to be very wet causing the ink may bead up on the silicone surface. Some may also render your DrawnBy: Washable Silicone Drawing and Colouring Mats stained and discoloured. Care FAQ
