Canfanni Glass Food Storage Containers 40-Piece Set – Borosilicate Glass with Airtight Locking Lids

Canfanni 40 Piece Glass Food Storage Containers with Airtight Lids is a complete set of borosilicate glass containers and BPA-free locking lids designed for airtight, leak-proof meal prep and organized kitchen storage.

This 40-piece kit pairs 20 durable borosilicate glass vessels with 20 matching high-strength polypropylene lids that snap shut with a four-sided locking system and silicone gasket. The set includes round, rectangular and square shapes across multiple capacities, so you can portion lunches, store leftovers, or freeze batches with confidence. Built to tolerate wide temperature swings and to nest neatly when not in use, these containers offer a long-lasting, low-waste alternative to single-use plastics.

How does this set keep food fresh and spill-free?

Every lid has a four-sided locking mechanism and a food-grade silicone seal that creates an airtight barrier to slow oxidation and prevent leaks. The secure closure reduces odors and stops liquids from escaping when the container is carried in a bag or placed on a refrigerator shelf.

• Four-sided snap-lock lids for firm, even pressure across the rim.
• Silicone gasket ensures a tight, food-safe seal.
• Effective on both dry and saucy foods to minimize spills.

Are these containers oven-, microwave-, freezer-, and dishwasher-safe?

The borosilicate glass bodies withstand rapid temperature changes and are safe across a broad range: from freezer temps to oven-safe limits when used without lids. Lids are BPA-free polypropylene and are microwave- and dishwasher-safe on top racks, but should not be used in conventional ovens.

• Glass temp tolerance up to extreme ranges for cooking and freezing.
• Lids safe for microwave reheating and dishwasher cleaning (top rack recommended).
• Avoid placing lids directly in oven or on open flame.

What sizes and shapes are included for meal prep and storage?

The set contains a thoughtful mix of round, rectangular and square containers in multiple capacities to suit snacks, lunches, entrees and batch-cooked meals. This variety helps portion control, makes stacking efficient, and ensures you have the right shape for different dishes.

• Round sizes from 32.8oz to 2.7oz for soups, sides, and small snacks.
• Rectangular options ideal for entrees and layered meals, from 35.2oz to 6.4oz.
• Square bowls for salads and desserts, ranging 27.1oz to 4.7oz.

How much cabinet space will this set save when not in use?

Containers nest inside each other when empty, cutting storage footprint by roughly half compared with non-nesting sets. The lids stack separately and fit compactly, so the entire kit stays neat on a shelf or in a drawer.

• Nesting design reduces volume when containers are empty.
• Modular sizes stack vertically for tidy storage.
• Lids organize in a separate, compact pile for easy access.

Who is this for: This Canfanni set suits home cooks, busy parents, and anyone who meal-preps, freezes leftovers, or wants a durable, low-waste alternative to plastic tubs. It’s also a practical choice for people who need reliable, leak-proof containers for commuting, office lunches, or packing kids’ meals, and for households that prefer glass for taste neutrality and long-term durability.
