I received Practico Outdoors Stainless Steel Cups in return for my honest review. Practico Outdoors Stainless Steel Cups is a sturdy set of cups. They are made of food grade 18/8 stainless steel. They are very durable and won't break, shatter or rust. These cups hold 16 oz. of liquid. They are perfect for the kids' juices, milk, sodas, etc. I really like these cups. These are great for taking on different outings. They're shatterproof so I don't have to worry about the kids dropping or breaking them. I can pack them up (they're stackable) and take them to ball games, cookouts, beach, picnics, etc. They're perfect for splitting drinks between my 2 & 4 year olds because neither likes to share. These cups are dishwasher safe and easy to clean. Overall, a nice replacement for styrofoam cups -- which aren't great for kids because they like to bite them. Highly recommend!!
