Razab 3300ml (112oz) Large Borosilicate Glass Food Storage Container - Square, Airtight Leakproof Lid

Razab 3300 ml (112 oz) is a large, square borosilicate glass food storage container with a silicone-sealed airtight locking lid designed for baking, storing, reheating and meal prep.

This heavy-duty glass container pairs restaurant-grade borosilicate with a BPA-free plastic lid that locks for leakproof storage. At 112 ounces it’s one of the largest single-piece glass food containers available, shaped to reduce wasted refrigerator space and built to move from freezer to oven or microwave (lid removed) for straightforward cooking and reheating. The design aims to replace disposable trays and cramped plastic tubs by offering a reusable, heat-resistant vessel for casseroles, roasts, batch cooking and large leftovers.

How does this container hold up during baking and reheating?

The Razab glass body is made from borosilicate, which resists thermal shock and tolerates high oven temperatures when you remove the plastic lid. That makes it suitable for baking casseroles or reheating large dishes directly in the glass. Use the lid only for storage and transport, not in the oven or microwave.

• Heat resistant up to 600°F (lid excluded)
• Thermal shock resistance up to 248°F for safe temperature changes
• Microwave- and oven-safe glass — remove plastic lid first

Is this container truly airtight and leakproof for storing liquids or sauces?

The container uses a silicone-sealed BPA-free plastic lid with locking clips that compress the seal to create an airtight barrier, minimizing spills and slowing spoilage. The lid locks on all sides to secure contents for fridge or transport, though for long-term freezing or extremely vigorous shaking, extra caution is recommended.

• Four-side locking clips for reliable seal
• Silicone gasket prevents leaks and odors
• Best practice: keep lid vertical when carrying liquids

How does the square shape and large capacity help with meal prep and storage?

The square footprint reduces dead space in refrigerators and cabinets compared with round dishes, letting you stack and arrange multiple containers more efficiently. At 3300 ml (112 oz) it holds full casseroles, large roasts or multiple meal portions, cutting down on the number of containers you need for batch cooking.

• Square shape maximizes shelf and refrigerator space
• Large 3300 ml capacity fits family-size meals and leftovers
• Sturdy glass base supports direct oven and microwave use (lid removed)

How do I care for and clean this container to keep it working long-term?

The borosilicate glass resists staining and odors and is dishwasher-safe on the top rack for easy cleanup. Plastic lids are also dishwasher-safe but avoid high-heat cycles to preserve the silicone gasket; handwashing the lid will extend its lifespan. Inspect the silicone seal occasionally and replace the lid if the gasket shows wear.

• Glass: dishwasher-safe (top rack recommended), oven/microwave-safe
• Lid: BPA-free plastic with silicone seal; dishwasher-safe but not oven-safe
• Replace lid if gasket warps or loses sealing performance

Who is this for: Home cooks, meal-preppers and small restaurants seeking a single, large-capacity glass container that can bake, store and reheat food without disposable pans. It’s especially useful for families, batch cooks, or anyone who prefers reusable, heat-resistant storage that reduces clutter and plastic waste. Choose Razab 3300 ml when you want one durable piece that moves from oven to fridge to tabletop, then locks down for spill-free storage and transport.
