I bought 4- 22" brackets, 2- 4" and 2- 34" for my cat wall. These worked out really well and look great. Easier alternative than drilling holes for actual "hidden" floating shelves. The only complaint I have on these brackets is how dirty they were- whatever was on the brackets made my hands black, which resulted in me having to wipe down my walls after putting the brackets on where they needed to be, but it wiped off fine with Dawn dishsoap and hot water. Order arrived quickly, in great shape and seller was quick to respond to any questions I had- definitely recommend!
