We've all seen it. The marbles, used bandaids and other unmentionables in those dusty tag sale bins we have bought. You overlook them, for the rare minifigure or two, the Harry Potter unbuilt sets that loom through the corners. Thought I had experienced the ultimate when I found some random child's palate expander in one. But just now, I can't even handle it - what appears to be some dehydrated former skin of a rodent, and various parts - and I was already part way through the bin. Mostly with gloves, mostly!!
