Nice looking set of 4 "raw wood" shelves. They are made of a very light material, which is good for the type of shelf they are. Easy to hang as they come with paper patterns to hang on the wall. (Very clever.) They look great and are pretty sturdy, however, I personally would never put anything excessively heavy on "floating" shelves of any kind, including these. I use them for vintage cameras. Great product(s)!
