Hiendure® Bathroom Faucet Vessel Vanity Sink Pop up Drain Stopper with Overflow Brushed Nickel;

Lavatory sink drain, precision manufactured by Hiendure.
This drain is constructed from heavy, genuine stainless steel, and is exceptional quality.
This is a push-button style drain; simply press the top of the pop-up to close, and another press to open.
Inside the drain is a very-smooth, spring-loaded mechanism that maintains a water-tight seal without the need for a leaky push-pull lever.
This drain is "Overflow Style" for use with standard sinks and vanities that have an overflow hole at the top of the sink bowl.
Drain is standard-size; designed to fit bathroom, vessel and wet bar sinks, or any sink with a drain hole from 1 1/2" to 2" in diameter (fits almost all sinks).
The drain exit, or waste pipe, is standard 1 1/4" size, although these drains can also be used with 1 1/2" traps and a bushing.
