Lot consists of 24 thin, aluminium rings, all the same, salvaged from computer hard drives.
Various thicknesses and slightly varying diameters, most will be in the range of 1 1/4" in outside diameter and 1" interior diameter x 1/8" thick. Probably some identical matching ones, but some vary a 1/32 of an inch or so in various measurements.
A few rings have a black mark on them, but that can be removed with lighter fluid or nail polish remover.
Where we get these: One of Bear's business ventures is salvage, and part of that business consists of processing e-waste. Normally, hard drives are cut or otherwise destroyed, then shredded. However, Bear processes them differently, and as a result has the opportunity to salvage unique & funky internal components that would otherwise be destroyed.
If you have ever taken apart a hard drive, you know it can be time consuming. Also, to get a lot of 6 identical rings like this is not easy to do, as there are usually only 1 or two in every drive, and they tend not to be identical from drive to drive.
