'hakims' chalk boards have a very special tough matt coating which does not allow chalk particles to form a layer. Thus the chalk writing can be easily erased without using a wet cloth. Delux boards have a laminated back. These boards are like a four-lined notebook - with 2-colour lines. The boards may be wall mounted or put up on stands. Features: No maintenance like repainting or regrinding of glass required. Colours available: Black , Blue & Green. Disclaimer: Stands are optional.
