Just like the classic Red Party Cups, these cups are now available with a more durable, reusable, eco-friendly design so that you can use it over and over instead of throwing it away and filling up landfills. With the double-wall construction, these plastic drink cups can be used for hot (not boiling) or cold beverages. These 16-ounce cups are made in the USA with BPA-free materials for safe drinking. Since the cups are made under strict U.S. laws they do cost a little more than cheaper foreign knockoffs, but be safe and look at the manufacturing country and certifications before purchasing any of these.<p>A clear, Snap-On lid comes with each cup and has a matching slider that opens for drinking and closes to protect your beverage. Although not entirely spill-proof, it will minimize a spill if the cup is knocked over. The extended mouthpiece makes it very comfortable for drinking. The see-through clear lids make it easy to see when refills are needed.<p>Also like the original party cups, these reusable cups come with grooved lines which provide a better, more secure grip and internal lines that provide a visual guide for measured pouring. Visible lines inside are at 1 ounce, 5 ounces, 12 ounces, and 16 ounces. These BPA-Free plastic cups are also great as a reusable smoothie cup or reusable iced coffee cup and make the perfect addition in your home bar, motorhome, boat, at the pool or beach. These reusable cups are a great choice for kids sports games, while tailgating, camping, bachelorette parties or for everyday use at home.<p>Plastic Cups have a large 3 inch imprint area for you to customize. Cups measure: 5.5" Tall, 3.75" diameter at top of cup, 2-5/8" diameter at bottom of cup. Adding the lid on the cup increases the total height to 6-1/8"tall on the drinking area tapering down to 5.75" tall at the opposite side.
