How to use

Measure the register or binder to confirm a height of 242 mm and ensure the spine circumference falls within 330–355 mm. Slide the register into the cover so the spine aligns with the adjustable section; verify that the cover sits flush along the edges and that corners are not folded. For best results, handle the cover by its edges while inserting and removing documents to maintain shape and prevent damage to the contents.

Usage recommendations

Use the cover in dry, indoor conditions and avoid prolonged exposure to direct sunlight or high humidity to maintain rigidity and prevent warping. When storing multiple covered registers, stack them flat or stand them upright on a stable shelf to preserve shape. Replace covers that show significant deformation to ensure ongoing protection of important documents.
