I ordered these to try out a bit ago. Within a few uses, I bought another 2 packs, and will have this on re-order from here on out.These are great little pouches for handling RV holding tank odor. Each bag has 10 palm-sized pouches made of a thin clear water soluble material. Inside is a find granule powder version of the typical blue odor control stuff you can buy at most RV stores or retailers.The thing I love most about these is the simplicity of them. After a pump-out, simply pull one out of the bag, toss it into the toilet and flush it. No drips or blue stains, no worries about measuring or guessing how much is enough, no granules left clinging to the bowl or blocking the stopper seal. Just drop it in, flush it, and it dissolves and opens in the holding tank after a few minutes.I can't believe I ever used anything else, and look forward to using this system long term.
