Reddit reviews Beseler Archival Safe-T 3-Ring Binder Box, 11-5/8"x 10 3/16" Inches for Camera - White

I use an archival binder with negative sleeves

You can find them on Freestyle/Amazon/B&H, etc:

Freestyle: Binder / Sleeves


Amazon: Binder / Sleeves

I had a few of these Archival Binder Boxes left over from my high school photo days. When paired with these C-line Binder Photo Storage Pages you have a tidy archival solution for your Wide shots. The equivalent I use for Mini shots in the same binders are these Print File Negative Sleeves. One thing to note is that neither set of sleeves is made for these format of photos. I can fit two shots in each pocket comfortably. The aspect ratio isn't exact for either type of sleeve so there is the smallest bit of play. The archival boxes are clutch here because they prevent the photos from coming free out the top of the page which would be a danger if you put these in a regular binder.

It's not as glamorous as a photo album but it keeps the dust and light out and still lets me flip through and browse.

Unrelated but hopefully helpful: The Google Photos team just launched PhotoScan. Before you load these pages up you can tear through the traditionally long process of digitizing instant film with this app. Not the same as sending them away to be digitized but it's free and gets you 90% of the way I would say.

PrintFile sleeves stored in archival binders.
