MTMP3 Black Mighty Tiny Master Plunger is custom designed to fit in those tight places such as the Bathroom Faucet and the Popup Sink Bowl Drain giving plenty of room to plunge. The Unique Patent Pending design produces maximum push pull action to agitate the most stubborn clogs. The Mighty Tiny is so powerful, that you will need to cover the water overflow porthole in your sink bowl to avoid water or air from escaping, this allows the Mighty Tiny to concentrate directly to the clogs. Perfect for everyday household, RV's/Travel Trailers in kitchen drains, bathroom sinks, floor drains, showers, tubs, and or bathtubs. Convenient size for easy storage, especially for under bathroom sink cabinets and RV's where space is very limited. 2 and .25 cups of water displacement gives you double the plunging power as a standard outdated rubber cup plunger. 1 Year Warranty.
