M MCIRCO glass food storage set 30-piece extra large with red airtight snap-lock lids, borosilicate oven‑safe bases

M MCIRCO 30-piece extra large glass food storage set is a durable borosilicate collection with airtight red snap-lock lids designed for meal prep, fridge organization, and safe reheating.

This complete 30-piece set includes 15 glass containers and 15 matching red lids in a variety of large sizes so you can store entire meals, batch-cooked dishes, and bulk leftovers without clutter. Made from premium borosilicate glass, the containers resist thermal shock better than ordinary glass and are meant for everyday use across fridge, freezer, oven (lids off) and microwave (lids off). The bright red snap-lock lids include silicone seals for leak resistance and convenient stacking to keep cabinets and refrigerator shelves tidy.

How large are the containers and which sizes are included?

The set is tailored for extra-large storage needs and covers a broad range of capacities so you can match portions to food types. Each size nests for storage when empty and stacks securely when filled using the locking lids.

• One 50.1 oz and one 44 oz container for casseroles or family-sized meals
• Two 37.2 oz / 33.8 oz range pieces for soups or main dishes
• Several mid-sizes (31.5 oz, 27.1 oz, 21.5 oz, 21.3 oz) for meals and sides
• Multiple smaller containers (16.9 oz, 13.5 oz, 12.5 oz, 10.5 oz, 7.3 oz, 6.3 oz, 5.4 oz) for sauces, snacks, and portioned meals

Are these containers safe for microwave, freezer, dishwasher, and oven use?

M MCIRCO borosilicate glass is designed to handle temperature changes better than standard glass, making these containers versatile for many kitchen tasks. For safety and to protect the red lids, remove lids before heating in the oven or microwave; lids are dishwasher-safe, as are the glass bases.

• Microwave: glass bases only, lids off for reheating
• Oven: glass bases safe at moderate oven temperatures; lids must be removed
• Freezer: freezer-safe for long-term cold storage without cracking
• Dishwasher: both glass and lids are safe on top rack; silicone seals resist staining

How reliable are the lids and are they leakproof?

The set uses snap-lock lids with integrated silicone gaskets that form a tight seal to reduce spills and extend food freshness. While designed to be leak-resistant for most liquids, lids should be properly snapped on and kept level during transport for best results.

• Four-sided snap-locks for a secure closure
• Silicone seal helps prevent leaks and keep odors out
• Lids are durable and engineered to resist warping or sticking over time
• Recommended to keep upright when carrying liquids for extra safety

How do these containers save space and simplify meal prep?

The set’s nesting bases and stackable design with locking lids maximize storage efficiency in cabinets and refrigerators. Using consistent shapes helps you organize meals, label portions, and free up counter and shelf space.

• Nesting sizes collapse together for compact storage when not in use
• Uniform lids allow stable stacking inside the fridge and pantry
• Multiple sizes let you portion-control and batch-cook without extra containers
• Clear glass makes contents visible for quick meal identification

Who is this for: This 30-piece M MCIRCO glass set suits busy households, meal-prep enthusiasts, and anyone who prefers reusable, non-plastic food storage. It’s especially helpful for families, people who batch cook, and home cooks who need extra-large containers for casseroles, salads, soups, and bulk leftovers while keeping kitchens organized and food visible. If you want durable glass that moves from fridge or freezer to oven and dishwasher-safe convenience (with lids removed for heating), this set provides a flexible, space-saving solution.
