You can never have too many lids! Swig slider lids are perfect if you prefer a more secure, splash-free option. Check out the care instructions regarding how to remove the slider for better cleaning.
The lid is BPA free, dishwasher safe and secures to the cup via a push-seal silicone gasket. The clear lid design seals tightly to minimize spills and maintain temperature while allowing you to see inside. It also features a straw friendly opening.
