This "flip straw" style lid is an accessory lid (purchased separately; water bottle not included) to enhance the hydrating experience of the 18 ounce Stainless Water Bottle. The lid fits securely on our 18 ounce bottle (and on our previously sold 32 ounce bottle), and allows for easy sipping and drinking of hot or cold beverages. It can be opened with a "one finger" flip.
The Flip Straw Lid measures approximately 8.5 inches in circumference (approximately 2.5 inches in diameter). The length of the straw itself is approximately 9.75 inches; the length of the straw can be cut to fit any wide mouth bottle (for our 18 ounce bottle, the straw can be trimmed down by approximately 2.25 inches; for our previously sold 32 ounce bottle, the straw can be trimmed down by approximately 1.25 inches). To achieve the right fit for your bottle, just trim the straw from the bottom.
(Note: This lid will not fit our previously sold 12 or 16 ounce Stainless Water Bottles)
