Question: Still have not answerd if they are acid free.
Document: I augmented that with dozens of homemade cards to separate many groups of photos by date and subject. I like that the box is so sturdy, and it's acid-free with no plastic. They stack well, too.
thought they would be a little bigger, i need to read closer next time before i buy, these are a few dollars cheaper at walmart.
Though I think these were priced a bit high, I am happy with the quality and the colors. I also think they should include pre-sized tabs for labeling. I am on a mission to pull apart all my old albums, scan the photos and store them here. Then, if I really love a set of pics I will use one of the on-line services to create a book. Meanwhile, I feel like my photos are securely stored both in these boxes and on disks.
This was the second one I bought and they are both fine for my uses. I recommend it for anyone.
They served their purpose on the shelf.
These boxes are sturdy photo storage boxes. They are large enough to hold DVD's in regular size cases and VHS  tapes. If the VHS tapes are in the oversize plastic, they won't fit in these boxes, unless you lay them lenghtwise. I  like the Thompson boxes as well if you can find them.

My box arrived completely unusable and busted up. I'd ordered another box of the same kind, and it arrived just fine and is pretty nice looking, but it was disappointing that the second one was a bust.
I'm in the  process of organizing some old 4x6 photos, and this storage box is perfect size for that. I may need to order a few more, but this is exactly what I needed for the job.
I have hundreds and hundreds of black-and-white family photos going back to 1900 and earlier, plus color photos from the past 40 years. They were either loose in a storage trunk or stuffed into Ziploc bags. The Pioneer box is great for storing 4x6 and smaller photos, front to back - almost like a recipe box or old card catalog. I don't know if I got 1100 in a box, but I filled up three boxes.
I bought this box to store the American postcards I accumulated on a 76-day cross-country trip this past summer. The cards from the European part of the trip I put in another box. But this one was great for all the USA cards. You don't have to use it just for photo or negative storage, which was it's original use.
Answer: Says this right next to the product photo: "Photo safe: acid free".
