I use them to hold order paperwork for individual customer jobs in production. When a job is complete all the tracking paperwork is already in one clear vinyl packet that is then filed in a binder when the item ships out. Inexpensive but durable enough for this use. My wife saw them and now also uses these for storing all her quilting knitting & crocheting patterns in loose-leaf binders. I needed to go with the 200 packs so I that have enough for my works needs.
Effectively displays what's put inside and each unit holds two pages plus up to a couple of inserts/pictures. Buying in bulk is the better bargain of course as opposed to buying smaller quantity packages.
I loved these sheets. I used them to protect pictures in a photo album.I could not find the old fashioned inserts with plastic overlays. These worked perfectly.
