BPA stands for Bisphenol A, an industrial chemical compound used in the manufacturing of strong plastics. Our only gripe is that sometimes a few water droplets splash when you press the button to release the spout, but otherwise the entire unit feels very sturdy and something that will potentially last you years.In BUILT, you'll find a collection of industrious, stylish and protective goods inspired by the city that never sleeps.
