Brownlow's Recipe Binder Card Holder Sleeves
Brownlow's splatter proof universal recipe card refill sheets come in sets of 10, and are side loading. They are made to fit Brownlow's Recipe Binders, and the space between each hole measures 2-3/4", in case you want to measure to see if they fit your own binder. They measure 6-3/4" x 8-3/4".
When putting two recipe cards in a slot, one pack will hold 40 recipe cards.
