The APS Liquid Chalk Marker set provides two white markers designed for creating clear, opaque lettering and drawings on smooth surfaces. Each pen features a 2 mm tip that allows for precise lines on chalkboards, glass, and signage, making them useful for updating menus or creating temporary displays. These markers are crafted from durable polypropylene and measure 13 cm in length with a 1 cm diameter, ensuring a comfortable grip during use. To start, you simply shake the marker and push the tip down to release the ink. Because the liquid chalk is wet-wipeable, you can easily clean the surface once your work is no longer needed. These tools are made in Germany by Assheuer + Pott GmbH & Co. KG.
