These ultra-fine chalk markers can be used with black and white boards. They produce beautiful writing on glass and plastic surfaces. They are filled with pigment ink, which makes the writing line intense and crisp.
The 0.9mm needle tip makes them a very precise writing instrument.
They are easily washable from smooth surfaces.
Since they are odourless and xylene-free, they can be safely used for indoor applications.
For optimum writing quality, stir the content thoroughly before the first use.
