A very efficient way of displaying words, messages and images that change regularly. The use of chalk on the whiteboards allows for messages to be rubbed and washed away when they need taking off or even changing. This is easily done and the new message can be added almost just as instantly. Several colours are available in chalk, allowing for several colours to be used when writing your message, the colours are eye catching and can be used to grab people's attention. The delivery of these items is free to the mainland UK.
