The Square 30/40/50mm is a pocket product that uses the classic Pythagorean 3/4/5 triangle. Handy for quick right-angle checks. Due to the 3/4/5 triangle not having round numbers for either angle except the 90-degree corner these have not been included on the product.
Part of the Original Collection. A warm and tactile set of products made in the UK from European recyclable and carbon neutral MDF that gives a beautiful textured look to the surface. The markings are all etched in to ensure they cannot be worn away over time and the back face is painted black to allow the pieces to move around smoothly on notepads and drawing paper.
