3M sells a good spread of most everything, including their 5557CIR-2(100) water contact indicator tape patches. These handy little patches change color when they come into contact with liquid water, allowing you to verify your products have stayed dry during shipment or storage. We’ve had questions recently about how many such patches you get in a single QTY. 1 order for this product. What is the unit of sale for it?
A QTY. 1 order for this part number will yield a satchel of 100 patches.
