矩形蓋子

The sizing guide is spot on—I checked the numbers on the bottom of my container and the lid snapped on perfectly. The silicone gasket seals tight enough that I can shake it without worrying about leaks.

The silicone gasket creates a proper seal that keeps my leftovers fresh for days, and matching the lid to the model number on the glass was surprisingly easy. Took me a minute to find the right digits, but once I did it fit perfectly and the color variation doesn't bother me at all.

Finally found lids that actually fit my glass containers without struggling. The silicone gasket seals tightly, and it's nice that the color varies a bit so they don't all look identical.
