Addyno 2 Pack Multi-Use Sink Plunger – Heavy Duty Silicone Drain Unblocker with Multi-Layer Suction for Kitchen, Bathroom & Bathtub Tired of drain covers that wash away as soon as water runs? The Addyno drain unblocker stays firmly in place thanks to its upgraded multi-layer suction ring design. Press down, and the stacked layers create powerful negative pressure that locks it onto the drain — even on slightly uneven surfaces or under running water. This 8-in-1 tool does more than just unblock drains. Use it as a sink stopper for washing dishes, an overflow cover to fill your sink deeper, an odor blocker to seal out sewer gas, a dustproof plug for unused drains, or a utensil hook on smooth vertical surfaces. Made from 100% recyclable, BPA-free food-grade silicone, it won't crack or harden like rubber. Easy to clean, too. Each pack includes two — one for the kitchen, one for the bathroom. Optimized for sinks, bathtubs, and floor drains. Not for toilets. For best results, ensure the drain surface is clean before use.
