Liquid chalk markers are a fantastic accessory to accompany Magnetic Planners and Boards perfectly. The vibrant colours feature a 3mm reversible bullet/chisel tip, write cleanly on magnetic products and dry to look like standard chalk without the mess or dust. Use the markers to add details to your routine boards or planners. Use them to create new pictures on blank magnets included with sets. They are a wet-erase marker so can be used on any non-porous surface and wiped clean with a damp cloth. Liquid Chalk does not work on standard chalkboards and will leave ghosting due to the porous surface. Compatible with all magnetic / whiteboard products Product Features: 4 pack of liquid chalk markers (4 colours) 3mm reversible bullet / chisel tip Use on any magnetic / whiteboard surface (even the fridge or other whitegoods) Wipe clean with a damp cloth How to use liquid chalk markers: Instructions for initial use and storage are included on packaging. Markers require pumping on initial use to draw the ink through to the nib. Excess pumping will result in excessive ink so take it easy when getting started. Chalk Markers are to be used under supervision. Not suitable for children under 3 years.
