Hidden interscrews. Very popular for menus as high quality durable covers can be combined with contents that is very securely held and easily replaceable.

Interscrews can be totally hidden as above. Or slightly semi visible...

Semi visible interscrews. On the outside no sign of binding at all. Inside pages are discreetly clamped together. Most of the qualities of hidden but a cheaper to make.

Visible interscrews. These have a practical visual honestly on the outside, although the most economic to produce of the set still render a high quality product when combined with fine materials.

Above the interscrews are used to visably bind the cover and pages, below the interscrews have been used to visably bind the inside pages.

All interscrews can be removed easily for clean conscious recycling.
