Razab Glass Food Storage Containers 80 oz (10 cup) 4‑pc x2 Set — Airtight, Leak‑Proof Borosilicate for Oven, Microwave & Freezer

Razab 80 oz (10-cup) borosilicate glass food storage containers are a 4-piece set (pack of 2) with airtight locking lids built for storing, reheating, baking and serving while preventing leaks.

This two-pack of Razab glass containers combines restaurant-quality borosilicate glass with four-clasp silicone-sealed lids to give you leak-resistant, stackable storage for meal prep, leftovers, and oven-to-table cooking. Each rectangular vessel holds 80 ounces (10 cups), fits neatly in the fridge or freezer, and can be reheated in the microwave or oven (glass only). The locking lids keep contents fresh and reduce spills during transport, while the durable glass resists stains and odors.

How do these containers handle everyday meal prep and storage?

They are sized for family meals and batch cooking, letting you portion soups, casseroles, salads, and sides in one container. The rectangle shape minimizes wasted refrigerator space and stacks efficiently to keep the kitchen organized.

• Each container holds 80 oz (10 cups), suitable for mains or multiple servings.
• Rectangular profile reduces dead space compared with round containers.
• Stackable design for compact fridge and pantry storage.
• Silicone-sealed lids create an airtight barrier to extend freshness.

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

The borosilicate glass body tolerates high temperatures and thermal changes, allowing safe use in ovens and microwaves for reheating or baking. The plastic lids are dishwasher-safe on the top rack and keep food sealed, but they are not oven- or microwave-safe—remove lids before heating.

• Glass safe in oven and microwave (remove lid before heating).
• Lids top-rack dishwasher-safe; glass dishwasher-safe but gentle cycling recommended.
• Freezer-safe for long-term storage without cracking under cold temperatures.
• Heat resistant up to high temperatures due to borosilicate composition.

How reliable is the airtight and leakproof locking system?

The lids use a four-flap locking mechanism and a silicone gasket to form an airtight seal when closed correctly. To ensure a full seal, align and snap flaps in pairs so the gasket sits evenly; improper closure may reduce effectiveness.

• Four-side locking flaps for a secure, spill-resistant seal.
• Silicone gasket provides airtight protection and helps prevent odors.
• Close flaps in matching sides first for correct alignment and sealing.
• Leakproof for sauces and liquids when lids are properly fastened.

What makes borosilicate glass a practical choice?

Borosilicate glass offers superior thermal shock resistance and durability compared with standard glass, making it ideal for oven-to-fridge transitions and repeated daily use. It also resists staining and retains flavors less than plastic, so meals stay true to taste over repeated reheats.

• High thermal tolerance reduces risk of cracking under temperature shifts.
• Non-porous surface resists staining and odor retention.
• Durable for long-term reuse, supporting sustainable kitchen habits.
• Clear glass lets you identify contents at a glance without opening.

Who is this for? Home cooks, meal-preppers, and families who want dependable, reusable cookware and storage that moves from oven to table to refrigerator with minimal fuss. Razab’s 80-oz containers suit anyone looking to reduce single-use plastic, organize the fridge efficiently, or prep lunches and dinners in larger batches while keeping food fresh and transportable.
