Chemically treated paper strips to test for acid or base (alkaline) solutions. Use the blue for acids, the red for bases. The more sophisticated pH test paper strip indicates pH from 1 (bright red) to 14 (dark brown). Values in between can be read by comparing with a color chart that comes with the strips. All have (100) strips of test paper per vial.

How you gonna wrap that dishwasher as a birthday present? Or that barbecue kettle for Christmas? Same way you wrap a moped. In our giant, heavy-duty gift sack. Made of red, cottony-nylonish-nonwoven stuff that's quite tough. Measures 36" x 22" across the bottom and is 48" high, with a white cinch ribbon at the top and a little 4" x 3-1/2" windowed gift-card holder, so they know just who bought them this great big present. Equally useful as a dust cover for a Sousaphone. Extremely presentable!
