This 30 oz. Stanley was recently purchased and used on a handful of occasions—only with water. I put it through my dishwasher once—there is a slight chip towards the bottom of the cup (pictured). There is also a bit of color coming off on the very bottom of the cup-around the barcode sticker (pictured). This Quencher H2.0 is generously sized (but not oversized) with an easy-carry, comfort-grip handle and a narrow base that will fit most cup holders. Long day of meetings? Rowing class? Trip out of town? Our durable 30 oz tumbler, made with recycled stainless steel, is up to the hydration challenge. The double-wall vacuum insulation will keep your water cold for 9 hours and iced for 40 hours. And to cap things off, there’s an advanced FlowState™ lid that features a rotating cover with three positions: a straw opening designed to resist splashes with a seal that holds the reusable straw in place, a drink opening, and a full-cover top. 90% recycled 18/8 stainless steel, BPA-free Recycled stainless steel icon inside the tumbler indicates your Quencher is made from sustainable materials Double-wall vacuum insulation FlowState™ screw-on 3-position lid Reusable straw Comfort-grip handle Car cup holder compatible (base diameter: 3.15 inches) Dishwasher safe
