Pyrex® 4-cup ronde donkerblauwe plastic deksels, 6-pack

The dark blue color makes these lids easy to spot in my cabinet, and the snap-on fit is secure enough that I’ve stopped worrying about leaks in my lunch bag. They’re sturdy and don’t warp in the dishwasher, which is exactly what I needed for my round 4-cup dishes.

I was tired of losing lids, so this 6-pack is perfect—the dark blue plastic feels sturdy and snaps on tight. Each one seals my 4-cup round dishes without any leaks.

Finally, lids that actually stay on when I shake the container to mix a salad dressing. The seal is tight enough that I’ve flipped a full dish upside down with zero leaks, and the dark blue plastic hasn’t stained or warped in the dishwasher after a month of use.
