The paper is ruled with a 2/10/20 mm graph pattern that fades subtly into the background, making your graphs more prominent. Each sheet is micro-perforated and punched with four holes for easy removal and filing in standard ring binders and lever arch files. Made in the UK from 100% recyclable materials, the paper fibres can be recycled up to six times. Size: 210 x 297mm.
