I also use the 2 X 2's that are stapled closed. I flatten down the crimped over staples, than put the 2 X 2's in my album using Lead Dog No PVC content 2 X 2 display sheets. Than the album goes in a large Rubbermaid container with a pouch of desiccant. I've read where some people use 2 X 2 Manila Envelopes for storage as well.
