Offered for your consideration: In Original Box! STILLPOINTS Damper ULTRA SS 1/4-20 Set Of 4 Vibration Isolation. I have a lot of photos showing them from all different angles. Now the details: all 4 are same height (roughly about 37-38mm), same weight, roughly about 224 grams (quite heavy, all 4 will weight just under 1 kilogram), but if you look on the top or perhaps the bottom, the part that touches the surface, 2 are flat, the other 2 have indentation, also the righting on the bottom of those flat are much lighter then the other 2, much darker. That being set, if you need 4 they will work as a set, no problem at all. Also if you don't need all 4 let me know, it can be worked out. If you care about my opinion I would say for used item they are very nice. I will gladly respond to any questions you may have.
