The high quality board surface is made of high-density HDF fibreboard and is overlayed with black varnish, which ensures the right contrast and prevents the chalk dust from penetrating the surface. Chalk markers can also be easily wiped off with a damp cloth or sponge. The blackboard surface is scratch-resistant. Suitable for writing on with chalk or chalk markers. The lightweight frame made of natural pinewood has been reinforced with staples on the back for extra strength. The board can be hung vertically or horizontally as required. The set includes hooks for easy mounting. The board is perfect for schools, kindergartens and the nurseries. They are an ideal solution for promoting your child's numeracy or spelling skills.
