I have no idea about these other than the price looks like one I couldn't refuse.

Three piece set, 12mm(1/2"), 18mm(3/4") & 25mm(1") for $3.99. Plastic handles but at that price if someone needed some beaters or wanted to modify or use for plane blades, it is hard to turn down.
Saw this in the ACE Hardware on line site while looking for information on a new cordless drill.
