Vault X zip binder, 9-pocket
Vault X
A side-loading zip binder with stitched pages. The sensible default for a master set.
No rings, so nothing presses a dent into the inner column. Side-load pockets do not dump cards if the book tips. 360 and 480 pocket sizes cover most sets. Do not overstuff a pocket.
Archival pages for a ring binder, if you already own a decent one.
Buy pages labelled polypropylene and PVC-free. Old soft PVC pages can stick to cards and yellow. If the binder has O-rings, the inner pockets still take a dent — D-rings are less bad, a zip binder is better. Top-load pages drop cards. Side-load.
