a little concerning considering a few of us use bathtubs. i'd suggest getting one of those lead testing pens to be sure.

I think i would be more worried about the amonia that gets in them sometimes

probably will have no effect on adults, i'd be concerned about kids though it can mess up the poor buggers development.

edit - can't believe i just made a "think of the children" comment. i must be slipping.

Probably the lead Timmy

Good job it wasn't the 'plastic' ones.
