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. Height adjustment is easy and intuitive! Just unscrew the wing nuts and adjust two shelves (top and bottom) to the desired width, depending on a canvas, poster or a whiteboard /chalkboard you have. The easel can be used in sets with our ALLboards: chalkboards, magnetic whiteboards, cork noticeboards or textile noticeboards. The easel is assembled and complete, ready to use right out of the box!
