-These high-quality 12oz. stainless steel white tumblers have a premium hard coat that provides crisp and vibrant color sure to last for years. Perfect for all hot & cold beverages. -Leak proof! All water bottles are leak proof - you may experience a couple drops coming out when first opening the lid, but that is just the water that was left in the spout. You can set these on their side, turn them upside down and the water will not come out! -Our water bottles are printed using a permanent sublimation process that ensures a vibrant, detailed design that won't chip or fade. -Sublimation printing is the process of transferring an image to a variety of materials (in this case water bottles) using high heat and pressure. We do not use vinyl for these cups! The design is printed directly onto the cup and is permanent – meaning it won’t chip or fade with proper care! INCLUDES: -Easy to use fliptop lid -Straw that connects to the inside -Double-wall insulated, stainless steel tumbler
