Celco 45 Degree Set Square 26cm Clear

This set square provides 45 degree and 90 degree angles. It is ideal for bisecting right angles, constructing isometric drawings, and completing standard geometry tasks at school or in a professional drafting environment.

Yes. The bevelled edge lifts the drawing surface slightly away from the paper, which helps prevent ink smearing when used with technical pens or fineliner markers. It also works well with pencils for everyday geometry work.

This listing is for a single 45 degree set square. If you need a complete geometry kit, consider pairing it with a Celco 60 degree set square, a ruler, and a protractor.

The set square measures 26cm along its longest edge. This is a standard size that fits comfortably inside most A4 pencil cases, stationery pouches, and desk organisers.

The clear acrylic is made from a durable transparent plastic intended for regular educational use. While all clear plastics can scratch if not stored carefully, keeping it in a pencil case or protective sleeve will preserve clarity and readability over time.
