Essential Values Kitchen Sink Stopper (STP-SS), 3-3/8", Stainless Steel Plug Replacement- USA Made

Forget the sink strainer / stopper combo products. This is one that works on all sink drains and doesn't leak. If you need a strainer, but an additional one (personally, I tip the stopper to the side to catch any leftover food). I've tried more than 3 stopper/drainer combos from Walmart (and their vendors) without luck and chose to just use a stopper. Plus, it took MONTHS to get a refund and have them cancel their contract with the company that sold the inferior products. I also absorbed the cost of the last strainer I bought because it took so long to get customer service to resolve my claim.

This sink stopper works well. It fits tight in the drain, so water stays in the sink. Just don't leave the stopper sitting in the sink away from the drain, then go fill the sink with water. I did this and the water moved it into the drain upside down. And with the knob facing downward, it was difficult to remove.
