Very high quality tube Shields. all new never used. I highly doubt you'll find a lot like this again. Multiple cases available, each bid is for one case of 324 pieces. These retail between $7 to $15 each. A tremendous savings great deal here.

A good money making opportunity with somebody with the time. Some recent family issues came up and I don't have the time myself.
