Perfect for a variety of drinks. The ergonomic opening makes it easy to sip directly. Features a secure locking tab so you don't have to worry about spills when you're finished. Made from BPA-free, phthalate-free, eco-friendly materials and is dishwasher safe. Unlike the standard 16oz set featuring the original US-made "iron retaining ring," this version thoughtfully includes an "stainless steel retaining ring."
