Does the container come with a lid?

No. It is sold as the container only, so you need a matching lid separately if you want a seal. Without one it is fine for dry goods or covered freezer storage with film.

Is it safe for hot foods and the freezer?

Polycarbonate handles freezer storage and normal dishwasher cycles. Let hot food cool before filling, since sudden temperature swings stress any rigid plastic.

Can it go in the dishwasher?

Yes, it is dishwasher safe. Top-rack washing and avoiding harsh sanitizers helps keep the plastic clear and free of clouding over time.

How does it compare with square storage tubs?

It holds the same volume in a round footprint, which is easier to scrape clean but uses shelf space less efficiently. Square tubs stack tighter in crowded fridges.

What is the actual capacity?

It is rated at 4 quarts, roughly a gallon. That is enough for a large pot of stock, a big batch of dough or several pounds of dry rice.

Will it stain with tomato sauce or curry?

Polycarbonate can pick up color and odor from strongly pigmented foods over time. Soaking promptly and avoiding long storage of turmeric-heavy dishes limits it.
