Found what I was looking for, fast delivery.

I have used these in previous homes. They are easy to install, protect the toilet tank parts from harmful chemicals, and helps maintain a clean toilet.

Got the starter pack that contained 2 units. Also ordered a bleach refresher pack to get free shipping. All arrived quickly and was easy to install.

Great instructions and got it done even with a KOHL. Instructions and a view were simple.

Order was correct, no problems
