What is it?

I've been collecting unusual objects for quite a while, and several years ago I started posting them on this site as puzzles for visitors to figure out what they are. Most of the items are mine but a few belong to others, if you aren't interested in tools there are plenty of other type objects that have also been posted.

For first time visitors I recommend this archive for a wide variety of some of my best pieces.

    These weren't sold as tumbling media, I bought a small, two inch high vial of these metal pieces from a school supply store several years ago.

  • 117. Regardless of how you bought them they are vibratory media for polishing/deburring metal and sometime plastic parts. This site only shows two of the many shapes used, which can be mixed to do the desired job. http://www.smsystemsindia.com/consmr.htm That type mix is what you show in the picture.
