Not easy to see (!), but these page protectors are acid free/archival, top loading and very good quality. They fit most 3 ring binders and 2 post albums, so can be used as refills for existing albums or for your own handmade books.
No white inserts, spacers or screws - just the protectors.
Crystal clear.
Dimensions are: 22.5cm wide x 20.5 high. Hole dimensions (inner edges) which may be relevant for a post bound album are 11.4cm
