LocknLock Airtight Food Storage Containers — 38-Piece Set, Leakproof & Stackable

Lock & Lock’s 38-piece airtight food storage set is a complete, BPA-free collection of leakproof containers and lids designed to keep pantry staples, leftovers, and snacks organized and fresher longer.

This large assortment combines multiple sizes and shapes—round, square and rectangular—with Lock & Lock’s four-hinge locking system and silicone seals to deliver dependable, stackable storage for the pantry, fridge, freezer, or on the go. The lightweight plastic construction makes the containers easy to handle on high shelves while still offering durability for everyday use. Lids are designed for dishwasher cleaning and containers are microwave-safe for reheating (lids not recommended in the microwave).

How do these containers prevent leaks and keep food fresh?

The set uses an enhanced silicone gasket plus a four-hinge locking mechanism that creates a tight, uniform seal around each lid. That combination prevents air and liquid from escaping, which slows staling and stops spills when transporting food.

• 100% airtight silicone seals
• Four-hinge locking system tested for durability
• Leakproof design suitable for sauces and dressings
• Clear walls for quick content checks without opening

Which pieces are included and how will they fit in my kitchen?

The 38-piece set mixes small prep containers and large food-storage pieces so you can store single servings, bulk ingredients, or family-size leftovers. A variety of shapes maximizes shelf and fridge space, and the clear, stackable design simplifies organization.

• Multiple small round containers for spices and snacks
• Several medium rectangular and square sizes for meal prep
• Larger rectangular containers for casseroles or bulk items
• Stackable profile reduces wasted shelf and fridge space

Are these containers safe and easy to clean?

All pieces are BPA-free to reduce exposure to certain plastics and are designed for daily kitchen use. Containers are microwave-safe for reheating; lids should be washed by hand or placed on the dishwasher top rack when manufacturer guidance advises.

• BPA-free plastic construction for food safety
• Microwave-safe containers for convenient reheats
• Dishwasher-safe containers for easy cleanup
• Durable materials tested for long-term use

How durable and reliable is the locking mechanism over time?

Lock & Lock’s four-hinge closure has been engineered and tested for repeated use to ensure long-term performance. The hinges and seals are built to resist everyday wear, making the set a practical investment for frequent use and active households.

• Four-hinge lock engineered for longevity
• Tested repeatedly to ensure consistent sealing

Who is this for: Home cooks, busy families, meal-preppers and anyone who wants an all-in-one storage solution to organize a pantry, manage leftovers, or transport lunches. The variety of sizes suits singles and large households alike, while the leakproof seals and durable locks make these containers a practical choice for school lunches, picnics, and daily kitchen organization.
