These chalk markers from edding are not only perfect for creative crafting at home, but they are also a popular tool in businesses such as restaurants, bars, or the glass industry. The opaque, odorless liquid chalk is water-based and can be wiped off almost any non-porous surface with a damp cloth. Unlike traditional chalk, your hands will not get dirty while using it. Additionally, the marker produces professional and elegant lettering or drawings. Furthermore, some of the colors fluoresce under UV light. The cap can be stored at the end of the barrel to prevent the risk of loss.
