Other philatelic items, such as plate blocks, miniature sheets, covers, lettersheets, etc., can be stored in stockbooks.
Several manufacturers produce individual stock pages that can be inserted into loose-leaf folders.
The sides are left unattached so that the pocket can be lifted open to place a stamp or a philatelic item.
This arrangement reduces the chance of damage, since unlike in a three-side-attached stock page the stamps are not inserted or pushed into a pocket.
Manufacturers of stockbooks and stock pages include Stanley Gibbons, Lighthouse, Lindner, Prinz, Safe, Supersafe, G & K, Davo, Schaubek, Vera Trinder, Multi Master, UNI-safe, Climax, Compass, Importa, Rapide and Hagner.
