The magnetic slider cover allows for easy, spill-resistant use. The crystal clear lids let you visually monitor the contents of your cup. Shatter-resistant and BPA-free, these lids are built to last.

In terms of specifications, the lids have an inner diameter of 3.15 inches (80 mm) and an outer diameter of 3.38 inches (86 mm). They are made of plastic and silicone, in a clear color with a black slider.

The package includes two magnetic tumbler lids and two magnetic slider replacements. It is recommended to wash the product before initial use. While dishwasher-safe, the lids should not be microwaved.

The magnetic lid slide is designed to prevent spills, but it is not intended to be completely leak-proof. The black silicone O-ring around the lid rim helps create a tight seal to minimize leaks and splashes.

Additionally, the thick lid construction helps insulate the beverage, keeping it cooler or warmer for longer periods. However, it is not recommended to store the sealed lid in a bag or leave it in a car, as it is not 100% leak-proof.

The high-quality plastic used in these lids is BPA-free, eco-friendly, shatter-resistant, and easy to clean. The magnetic slider can be smoothly operated and removed for convenient washing.

The crystal clear design of the lids allows users to easily see the contents of the cup and monitor the drink level. The drinking hole enables direct sipping or the use of a straw, without the lid touching the nose.
