I had recently purchased three 30oz stainless steel tumblers from my son’s travel soccer team that came with lids that had openings that couldn’t be covered. I am not a huge fan of having an open drink when I am outdoors watching sports. These slider lids were the perfect solution to my problem! I received two clear lids with slider closures that will fit any 30oz tumbler, regardless of brand name. They came neatly packaged in a box, wrapped in bubble wrap, perfect for gift giving! The lid fit snugly to my cup, due to the black rubber seal ring, although I do believe it will leak if left turned on its side or turned upside down. The slider on the lid was difficult at first to open and close but with time and use, it became very easy to do like it should be. These lids are also perfect for keeping down spills while traveling with your tumblers in the car. A straw can still be used with the slider open but then you won’t be able to close it unless you use a bendable straw to put down inside the lid when not in use. I received this product at a discount in exchange for my honest and unbiased review.
