Review on Iris Clear Photo Storage and Craft Case, 4x6 Inches, 10 Pack - Organize and Embellish Your Memories! by Amy Punswick

They all snap open and are a good size. By learning the correct positioning, I pass on what I have learned. Don't keep them on a wooden shelf or in a wooden chest, they will eventually get soaked and it will be quicker than storing them elsewhere and they will no longer be acid free. I bought some large storage boxes from Iris to store here, they were cheap, 6 for $26 I think. I will keep this under my bed so they stay acid free for a long time.
