If I could pick one cup to use this would be it! Holds 40 oz, stainless steel straw with a silicone top, comes apart so it’s easy to clean, fits in cup holders, and the lid LOCKS so it doesn’t spill! Comes in a bunch of color options! This cup goes everywhere with me :) LTKSummerEdit LTKFindsUnder50 LTKGiftGuide
