Supersafe Stockbooks are like no other stockbooks in the world. Other stockbooks have strips with razor sharp edges - which can tear stamps.
Supersafe stockbooks are different. Each glassine strip in the white paged stockbooks is 'machine rounded' - no more razor-sharp strips that can damage stamps as you insert them.
White page stockbooks have glassine strips and interleaving; black page stockbooks have acetate strips and interleaving.
(16 page stockbooks have 8 pages, or leaves, total; 32 page have 16 total pages; 64 page have 32 pages, total. Front and back of each page are counted, as in a book, in the page total.)
