Use this 8x10" (200x250mm) sheet of blue litmus paper for testing or confirming acid water splatter or leaks, only $1.50. They can also be ordered as large as 20x24" (500x600mm); but minimum order of 100 sheets is required.
You can use a paper cutter to make your own custom sized strips from this sheet. Or, buy as short, narrow precut blue litmus test papers in a stoppered bottle.
