The OXO Good Grips Toilet Plunger and Canister is designed to open when you lift the Plunger and close when you replace it for neat and hassle-free plunging. The flat-top handle provides a secure, comfortable grip while you work. The Plunger head works on all toilets, including low-flush models. The ventilated drip tray contains any excess water and allows it to evaporate. The tidy Canister keeps the Plunger out of sight when not in use.
