This is a refill for Kao's Kitchen Haiter drain disinfectant and slime remover. It is unopened, and I am selling it because it became unnecessary after changing my system kitchen. This item will be shipped via regular mail. Please note that we cannot be held responsible for postal issues such as non-delivery. If you wish, I will include 10 unused deep-type long water-repellent stocking nets. #Disinfectant #Drainage #Drain
