Liuruiyu Glass Meal Prep Containers 10-Pack 21.6oz — Airtight, Oven & Freezer Safe

Liuruiyu 10-pack 21.6oz glass food storage containers are airtight, leak-proof meal prep and storage boxes built to go from freezer to oven and dishwasher safely.

These 10 uniform 21.6 oz (640 ml) glass containers with locking lids simplify planning, storing, and reheating meals without swapping dishes. Crafted from heat-resistant glass and BPA-free components, they let you portion lunches, keep leftovers fresh, and transfer between kitchen appliances with minimal fuss. The snap-lock lids deliver a reliable seal to reduce spills in transit while the standardized size helps stack and organize pantry or refrigerator space.

How do these containers make meal prep faster?

Having a matching set of ten identical 21.6 oz containers speeds up batch cooking and portioning — you can prepare multiple meals at once and store them uniformly. The clear glass helps you identify contents at a glance, and the stackable design saves space when storing prepared dishes.

• Ten equal 21.6 oz portions for consistent meal sizes
• Transparent glass for quick content identification
• Stackable shape to maximize fridge and pantry space
• Locking lids ready for transport or grab-and-go meals

Are these safe to use in the microwave, oven, freezer, and dishwasher?

Yes — the glass bodies are made to tolerate high and low temperatures so you can reheat, bake, freeze, and clean them without switching containers. Remove the lids for oven use when recommended by the manufacturer's guidelines and avoid sudden extreme temperature shocks to preserve the glass over time.

• Oven- and microwave-safe glass for reheating and baking (lids off for oven)
• Freezer-safe for long-term storage of meals and leftovers
• Top-rack dishwasher safe for quick cleanup
• Durable glass resists staining and odor retention

How reliable are the lids at preventing leaks during transport?

The lids use a locking mechanism to form an airtight, leak-resistant seal that helps prevent spills during commuting or picnics. While designed for everyday transport and storage, avoid pressing the container flat or placing it on its side with highly liquid contents to further reduce any risk of leakage.

• Four-side locking clips for a tight, secure seal
• Airtight gasket keeps food fresher longer
• Reduced chance of spills during packed lunches or travel
• Easy-to-open clasps for convenient access

What materials are used and are they safe for storing food?

The containers pair heat-resistant glass with BPA-free lids and silicone seals to provide a safer storage option than many plastic-only solutions. Glass won’t absorb stains or flavors and the BPA-free parts reduce concerns about chemical leaching when heating or storing food.

• Heat-resistant glass body that resists staining
• BPA-free lids and silicone gasket for food safety
• Non-porous surface that maintains flavor integrity
• Made for repeated use to reduce single-use plastics

Who is this for? These Liuruiyu containers suit busy households, meal-prep enthusiasts, and anyone who wants a durable, appliance-safe set for lunches, leftovers, or batch cooking. If you value consistent portion sizes, clear visibility of stored food, and the convenience of moving items from freezer to oven to dishwasher, this ten-piece set fits those needs while helping organize kitchen storage and simplify weekly meal routines.
