The Liquidraw T/Square for drawing is brand new with all original packing and box. I only opened it in order to photograph it. As far as I can tell, the 60cm T/Square is made of Pine wood but I’m no expert. It is a light and portable design. The ruler is used on drawings boards to get straight lines and work out measurements. There is some space either side of the 60cm measurement printed on the T/Square. It even comes with a screw driver and screws. Please do not hesitate to ask any questions Liz
