Ci Dental Floss Set of 4 * Non-wax, Non-flavor: 1 piece, 50.3m * Waxed, Mint: 1 piece, 40m * Waxed, Mint, Fluoride-treated: 1 piece, 40m * Waxed, Non-flavor: 1 piece, 40m This is a set of one of each, so it's a great way to try them out. Brushing alone isn't always enough, so this helps prevent cavities and is a great value because you get a lot of floss. I also have other floss products for sale, so please take a look. It will be reinforced with cardboard, placed in an envelope, and shipped via Mercari delivery.
