Lubise lid27 Magnetic Slider Replacement Lids for 20 oz Tumblers, 3-Pack

A magnetic slider gives these replacement lids a movable opening that can be closed between sips, while the clear design lets you see inside the cup. The set includes three lids intended for compatible 20 oz tumblers, making it a practical way to replace worn or missing covers without buying another cup.

Each lid is listed as BPA-free and has a 3.15-inch diameter. Compatibility depends on matching the lid to the cup, so check the tumbler’s opening before ordering.

Usage tips

Use these as replacement covers for a compatible tumbler, not as a universal lid based on the cup’s stated capacity alone. The product is described as compatible with 20 oz YETI tumblers, Ozark Trail, and old-style RTIC cups, as well as other tumblers of the same size. The listed diameter is 3.15 inches, matching that measurement is a more useful check than relying only on a brand name. The product title also mentions mugs and lowballs, but the detailed fit guidance centers on 20 oz tumblers, so confirm the specific cup before choosing these.

The slider opens and closes with magnets, and the lid has a double-sealed design. Those features are intended to help contain splashes and keep debris out during travel, but they should not be taken as a guarantee against leaks. The care instructions specify hand washing only. The removable lid and gaskets may also make cleaning more manageable, though the magnetic area deserves attention during washing.

Why it’s worth it

Three lids in one set can be useful when replacing more than one worn cover or keeping spares on hand. Compared with a basic lid that has a fixed drinking opening, the magnetic slider offers a way to cover that opening when it is not in use. The clear plastic also makes it easier to see the drink level without removing the lid.

Buyer feedback is mixed on the parts that matter most over time. Some customers say the lids fit their 20 oz cups and are easy to take apart for cleaning. Others report magnets coming loose, seepage around the magnetic closure, or cracking after heat exposure. That makes fit and closure function worth checking when the lids arrive, the manufacturer’s care guidance is hand wash only, not a heat-use rating.

Key features

The set contains three reusable, round replacement lids made from plastic, the materials information identifies ABS and also describes the lids as AS, so the exact resin is not consistently stated. BPA-free is listed as a material feature. A magnetic slider, double-sealed construction, and clear finish are the main design details. The stated use is travel, with splash and debris protection as the intended benefit rather than a promise of leakproof performance in every position.

What matters more here: a familiar brand name or a measured fit? For a replacement part, the opening diameter and cup style are the practical checks. These lids are presented for specific compatible cups, not as a one-size-fits-all option for every insulated mug.

When it makes sense

It suits you if you already own a compatible 20 oz tumbler and want several replacement lids with a sliding closure. It may also suit a household that wants spare covers ready for different cups. You may want to skip it if you need a lid for a different opening size, want documented dishwasher-safe care, or require a closure with no mixed reports about the magnet and leakage. Those concerns come from customer feedback, while the product details specify hand washing and compatibility checks rather than universal fit.
