The base of the ink composition of the UNI Chalk White PWE-5M WHITE marker consists of special chalk and polyacrylates. The liquid consistency allows for easy application of the chalk paint on almost any smooth surfaces: metal, plastic, glass, stone,... and porcelain. This chalk marker with a bullet tip allows you to create a line thickness of 1.8 to 2.5 mm. The marker can be used in various fields for all sorts of tasks: in schools - for drawing on boards, in bars and cafes - for signing price tags, creating signs and advertisements, in various industries - it can be used for marking parts, in design - for creating decor and crafts. Essentially, UNI Chalk is the same as chalk, just in a more convenient form that doesn't stain your hands. The marker tip is durable and wear-resistant. Writings made with UNI Chalk are resistant to precipitation (if it rains, it won't wash away the writing), but at the same time, the writings can be easily wiped off with a damp cloth using light circular motions.
