The Radii set is a collection of incrementally increasing radii for rounding corners. Starting at 5mm and increasing at 5mm steps to each subsequent corner up to 60mm. The 3 pieces fit inside each other and allow for a number of the radii to be marked with either an internal or external curve depending upon requirements. All pieces include 10 degree marks on the inside and outside edges and the first piece also includes centre hole cutouts for all the different radii. 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. 115 x 105 x 3mm
