Screen printed marking application makes it last long
Along with a drafting table, board, pencil, and chair, a T-square is a must-have item for technical hand drawing.
I have included a range of lengths and materials so you are able to find exactly what you are looking for. The metal rulers will last longer and are more durable, but are more expensive than the plastic options.
Pro tip: if you will be using it as a cutting edge, go with a metal ruler instead of plastic, this will prevent ruining it with your knife.
