Boards and dusters are commonly seen in traditional classrooms and other educational institutions. Boards are usually available in two types: whiteboards and chalkboards. Whiteboards have a writing area that is made of plastic or acrylic. It is written on with special whiteboard markers that can be easily wiped off with a duster. The markers are generally red, black, green, or blue in colour. The dusters have a handy rectangular shape and are fitted with a sponge or cloth on one side. Duster rubs off the chalk or whiteboard ink on the board so that the instructor can begin again. Some of the dusters have provisions for a marker holder as well. Chalkboards are usually black or green in colour. The board duster prices differ depending on the brand you are buying from. Some of the brands that sell boards and dusters online are SRIRATNA, Techfab, Big India Mart, Homedmart, MP MART, and Eduway. Double-sided boards are also available which have a whiteboard on one side and chalkboard on the other. Boards and dusters differ in their dimensions. Some of the popular sizes for boards are 60.96 cm * 60.96 cm, 45.72 cm * 60.96 cm, 30 cm * 30 cm.
