CUP LID : Around 2.75" in diameter, with an inner diameter of about 2.25". These lids are just for 16oz beer can glasses. The 0.35" straw hole works for most straight or curved straws. Great for adding to your collection or replacing a lost or damaged lid. SAFE 16 OZ TUMBLER LIDS: Our 16 oz acrylic lids are made of quality, BPA-free acrylic. Unlike bamboo lids, they won't get moldy. You can trust them with hot or cold drinks Dishwasher safe SPILL PROOF AND SPLASH PROOF: The 16oz glass cup replacement lid has double-sealing tech. It keeps air out, preventing spills, especially when you're filling hot drinks or on the road. This tight seal also keeps your drink hot or cold longer. There's a silicone gasket to stop splashes when you tip it. Check out our website and social media: website: www.weaveystudio.com Instagram: weaveystudio Facebook: WeaveyStudio TikTok: weaveyweavey
