Magnetic binding
A magnetic clip for holding sheets of paper that lets you add, remove and reorder without perforating and without destroying the set.

We have been binding the same way for two thousand years: by punching holes in paper.
Stitching, staples, rings, spirals. Every known binding system shares the same flaw: to join sheets you must perforate them or press them permanently, and to reorder them you must take the whole thing apart. The move was to replace the mechanical joint with a magnetic one housed in two side sections, so the set holds firmly enough to handle and opens without destroying anything.
The principle
Two laminar bodies with facing magnetic elements producing adjustable attraction between sections, without perforating the sheet.
The design
Laminar body with a foldable second face, magnetised side sections and adjustment to the thickness of the set.
The protection
Description, claims and drawings filed with the Spanish Patent and Trademark Office, with the utility model granted.
