Bonded leather is a well-known, reliable leather substitute. Milled pieces of leather, latex and oils are combined to produce it. 90–95% of the ingredients of the mix are natural products. The reconstituted leather makes a perfect base to write on, particularly if you are using a ball-point pen. These pads feature a formidable thickness of 3.5 mm and are highly flexible (so they don’t get creases or dog-ears), and the surface gives a little when you write on it. It’s also warm to the touch and repels liquid. Likewise, greasy fingerprints have no chance.
