    Poor packaging

    I now understand why my 1st package was destroy by shipper... unfortunately when I received my new shipment which was on time and customer service was very helpful so that part was great. But the packaging.... the person who wrapped the 2.5gal zerotol container, they didn't check the cap or tighten it and tape it in place. I'm not sure if they are new or what but regardless when I opened the bag the inside of the garbage bag that was used was covered in zerotol and when I had to reach in to grab it I received a slight h2o2burn on my hands. I'm not even mad about my hands but the packaging job was terrible.
