Celco T Square 45cm Clear Perspex Edge

Yes. The Celco 45cm T Square has a clear Perspex edge on both sides and is fully ambidextrous. It can be used comfortably by both left-handed and right-handed users without any adjustment.

The ruling edges are made from clear Perspex (acrylic). This transparent material lets you see your drawing beneath the edge, which helps you align lines accurately without lifting the tool.

It is well suited to art, graphics, and technical drawing subjects at school, as well as geometry tasks, architectural sketching, and any project requiring accurate right angles and true horizontal lines on large sheets.

This listing is for one Celco T Square 45cm. It is sold as a single unit, making it easy to purchase exactly the quantity you need for your classroom or workspace.

A T square uses its stock (the perpendicular head) to register against the edge of a drawing board, allowing you to draw consistent horizontal lines across the full width of your sheet. A standard ruler does not offer this guided, repeatable alignment.
