I purchased this from Amazon and tried to attach it to a chair, but realized I had the wrong size, so I'm listing it for sale. The Amazon description stated it was for diameters of 14-18mm. It's round, and comes in a pack of 4. No pets or smokers. Due to shipping considerations, I may remove the contents from the box and only ship the items themselves.
