About this item

• Compatible With: Designed to fit most 20oz tumblers with a 3.15 inch (80 mm) mouth diameter, such as YETI rambler, Ozark Trail tumbler, Old Style RTIC tumbler, and similar mugs.
• Splashproof and Heat Insulation: The black silicone O-ring securely wraps around the lid rim, preventing leaks. Additionally, the thick lid helps maintain the temperature of your beverage, keeping it cooler or warmer throughout the day.
• High Quality Material: Constructed with high-grade plastic, our lids are BPA free, eco-friendly, shatter resistant, sturdy, and easy to clean. They are dishwasher safe, but please avoid using them in the microwave.
• Magnetic Slider Lids: The convenient magnetic slider can smoothly switch positions and be easily removed for cleaning. Although the magnetic lid slider prevents spills, it is not completely leak proof. The drinking hole allows you to sip directly or use a straw, without touching your nose while drinking.
• Crystal Clear Lids: Our Magnetic Tumbler Lids are transparent, allowing you to easily see the liquid level and determine if a refill is needed.
