Richards Acrylic Closet Shelf Divider and Separator 6 Pack- Great for Storage and Organization in Bedroom, Bathroom, Kitchen and Office Shelves, Clear (9875300-3)

Work exactly as described, super easy to install, and very sturdy. For any wondering as I was, you can absolutely use these for bookshelves. I was unsure if these would work when I bought them, questions like would they be sturdy and stable enough to hold up under the weight of books? But I took the chance and they're perfect.I needed to add dividers to a very long bookshelf in my young daughter's room because everytime she removed a few books they would lean and fall over and make it impossible for her to put them back in. By getting these dividers we not only could sort her books into easy to find sections, but by having them in smaller sections they no longer fall over and its easy for her to put them away.They lock into place and don't move once locked down. Even though they aren't as wide as our shelf is deep, they still get the job done. Just be aware if you have an extra wide shelf like we do you'll have to make sure your books are between the dividers which may leave a gap behind depending on the overall size of the book(s).Overall great item and I'm actually looking for reasons for how I might use them in other areas of my home. Would buy more if I find additional need for them.

I have built in shelves in my closet and these dividers help clothes from tipping over and mixing. Keeps things organized.

Pro: Arrived quickly and they're fairly sturdy. They worked as shown in photos and installed over my extra thick shelf edge. Con: It took me a minute to figure out how to attach the first one but after I did the rest were easy. It doesn't take much to make them lean at bit if clothing is tight on one side. I think the attachment "clip" is unsightly. I solved it by pulling my clothing out a little to cover them.

Shelves worked well to separate sweaters on a shelf. At first, didn't realize they are adjustable for the width of the shelf, but they look to fit any size of shelf you most likely have. The little rubber bumpers on them (similar to ones use on cabinets) can come off, so watch that when you install. Otherwise, they do the job of keeping your shelf organized.

I like the fact that these are adjustable. They can work with different sizes/thickness of shelves. But they are very flimsy.

I got these because they are the only closet shelf organizers that have clamps that open enough to fit on our closet shelves. So far, they have fit securely. They keep the piles of closet stuff organized and visible. They take some figuring out because there are only very sketchy instructions, and I don't think they would hold up to heavy objects. They work fine for sweaters.

This is plastic junk. One of the dividers arrived broken but I didn't realize it until after I threw away the box so now I cant return it easily. Don't buy!

First of all the shipping time was excellent. Had it in a day which was terrific. I used the dividers to separate my purses in the closet. Easy to install, sturdy and don't slide, and the looks make the shelf very organized. I love them and would recommend them for separating sweaters, towels, books, and your own idea. A little pricey but they are worth it.
