Up for sale here is a set of 3 Mapleshade Radiused HeavyFeet. These are heavy, solid brass, weighing in at a pound and a half each. There are 1.5 inches in diameter, and 2 inches tall.
These are lightly used, and in mint condition with no dings or scratches. The markings and coloration you see in the photos are because they are natural solid brass, without any coating; eventually they will darken and become tarnished, and will need to be polished with Brasso or a similar brass cleaner.
Use them under any piece of audio/video gear to eliminate vibration and help with airflow. Mapleshade sells a set of three of these for $114.00. I will sell these for $75.00, which will include free shipping in CONUS. (The free shipping is a deal for these, because of their weight.)
