PHYSICS CHARTS

CHARTS: All Charts made of Water proof, Wrinkle free, flexible, fibre reinforced PVC sheeting (Rexine) these charts are strong and durable unlike the paper charts. They do not wear out, wrinkled or get

spoiled, nonglare black surface provides an ideal setting for the fig. The colours are special P.V.C. water

proof paints, guaranteed to be permanent. All Charts are 125x100cm unless mentioned otherwise.
