In very good condition. All you need is some plastic tubing and compressed air. Each leg has 4 mounting holes so you can mount them on almost anything. Or you can just rest them on a table top. If you currently have an optical breadboard on table and want to isolate it from vibration this is the way to go. Each Leg measures approximately 6 inches tall. Price is for a set of 4 legs. 7 day Right of Return if not completely satisfied. I have several sets.
