Pyrex® 藍色蓋子，用於6杯長方形收納容器

Finally found a lid that actually stays on securely without cracking. The dark blue plastic is surprisingly sturdy and clicks right into place on my 6-cup dish.

I was a bit worried it wouldn't seal tightly, but the lid locks on securely and keeps leftovers fresh. The dark blue color is nice and easy to spot in the fridge.

The seal clicks shut with a satisfying snap and stays tight — no more cracked lids or fridge leaks. It fits my 6-cup rectangular dish perfectly and the dark blue color hides stains better than the clear ones I've had before.
