These live edge sconces are made from logs, dried and sliced. Keyhole grooves are routed in the back so they look like log slices floating on the wall. There will be 2 keyholes of each to easily hang on screws (not supplied) for snug fit against wall. You may choose one or a set of two or three sconces. If purchasing a set, each sconce will be cut from the same log so the set will be similar in appearance. The approximate dimensions for the sconce listing are as follows: 4-5" diameter x 2-3"H 5-6" diameter x 2-3"H 6-8" diameter x 2-3"H. Because these will not be a perfect circle, the dimensions above are the diameter of the log before cutting off the back part that is flush against the wall. >For instance, most of the 5-6" sconces will be 5" front to back and wider side to side. >Some with irregular shapes may have more of an average dimension. i.e. A 6-8" sconce may be 5" deep and 8" wide or 7" deep and 6" wide, etc. The dimensions will vary due to nature of logs but will be close to what I have listed. If you have a particular need or request either sizing or coloring / wood grains, please let me know in the notes section at checkout. Or you can message me prior to purchase to ensure I can accommodate your request. They are sanded smooth & rubbed with Tung Oil for preservation and to bring out the natural beauty of the wood grain patterns.These are simple to hang. I suggest you use 2 1/2-3" long screws that are screwed into a stud. I hung mine using only one of the keyholes in the pictures. Even hanging on just one screw, the sconce is very sturdy.
