LunchBots Thermal 8oz/12oz Replacement Lid, 3-Inch Diameter, Dishwasher Safe

The dog got to my daughter's original lid and I thought the thermos was toast. This replacement fits the 12 oz Thermal perfectly — screws on smooth, seals tight, soup still hot at lunch. Ordered a spare immediately.

Fits my 8 oz jar exactly as described and doesn't leak. Only knocking off a star because it arrived a bit scuffed in the packaging. Function is perfect though.

Exactly what I needed, no leaks.

I've owned my LunchBots thermal for five years of daily use and the gasket on the original lid finally wore out. Rather than buying a whole new jar, this lid brought it back to factory condition. Threads line up cleanly, the silicone is thick, and it goes in the dishwasher top rack without warping. Companies that sell replacement parts deserve our business.

It fits and works, but the first week it seemed loose. After a few washes the silicone settled and now it's leakproof. Patience required.

One for each kid's thermos. Cheap, leakproof, dishwasher safe. Done.

I have an older 8 oz thermal and this lid only catches the threads intermittently — sometimes it seals, sometimes it doesn't. Might be fine for newer jars but I can't rely on it. Disappointing since it's advertised as fitting.

My old lid had a cracked gasket so the thermos went lukewarm by noon. New lid, and pasta stays hot for six hours again. Cheaper than a new jar and it took two minutes to swap.
