Unless otherwise indicated in the product data sheet, our magnetic chalkboards are writable with chalk or with Securit liquid chalk markers.
In our shop you can find the markers that we recommend to our customers, branded Securit.
Those of other brands can leave halos or marks, especially if you use dark colours on light-coloured chalkboards.
In our shop you can also find Securit spray cleaner, specifically designed for their liquid chalk markers.
