Finding more than a few A4 sheets was curving the standard pockets I was using and a reasonable load in a ring binder getting frequent use would even cause them to break at the punched holes, I looked for an upgrade. These pockets are stronger, bigger, better and proved a wiser choice for keeping papers neat. Definitely worth the money.
Nice strong pockets. Good customer service. Recommend that supplier state the size of individual pockets in the description as this would be useful but is not reflected in the pack size dimensions. The pockets are wider than normal, but obviously not as wide as the pack itself and were JUST too small for some of the things I wanted to put in them (e.g Radio Times covers)..
