Tuff to find

The almost generic name for a plastic pot scrubber or plastic scouring ball used to be "Tuffy." They became difficult to find. Then we used to find a little stack of scrubbers in a mesh bag; there'd be an orange one, a yellow one, and a green one. I can't remember who packaged these, but I once saved the cardboard atop the packaging because I liked the graphics. Our most recent acquisition was a pair of "kitchen scrubbers" from Quality Mop & Broom of Humble, Texas. The contents of this "2 pk." are made in Mexico and are intended "for pots and pans, tableware, etc." and are "not recommended for delicate surfaces." I'm not the one who needs these items; I keep my own cast-iron cooking vessels seasoned very well.
