Toilet bomb helps your toilet to smell fresh and helps make cleaning the toilet easy. 1 jar has 12 honeycomb. Minimum order is 5 jars. Just drop one in your toilet bowl let it bubble put 1-2 in your toilet tank. Once it stop bubbling flush your toilet. It’s homemade and safe. You could try using it for your shower head as well. I don’t have a water softener so water crystallized and difficult to clean so I cover the shower head with a zip bag out some of the toilet bomb in it and put some water let it sit whole night and it helped clean the shower head.For more inquiries please just private message.
