Best square food storage containers with glass lids

Top pick: Bormioli Rocco Frigoverre 3-piece square set — three nesting squares (3, 7 and 12 cups) with tempered glass lids that seal properly, freezer-safe and BPA-free. It's the set that covers leftovers, meal prep and lunch in one go, and it's sold at several stores, so you can pick your shop.

Who the others suit:

• Freshbox 3-piece set — the simplest buy if you want big family-size squares with lids included.
• PlanetGoods 6-piece set — best if you want more containers for the money and dishwasher-safe convenience.
• Square glass containers at The Home Depot — borosilicate with silicone-sealed lids; good if you want two generous sizes rather than a stack of small ones.
• PlanetBox medium square — a single container to try the shape before committing to a set.

Skip the fluted and 12-pack ribbed sets: round-ish and plastic-lidded, not what you asked for.
