Razab Glass Food Storage Containers 52 oz (6.5 cup) 4‑Piece Set — Borosilicate Rectangular, Airtight Silicone‑Seal Lids

Razab 52 oz glass food storage set is a 4-piece collection (two containers and two locking lids) made from borosilicate glass for airtight, leak‑resistant storing, baking, reheating and serving.

These rectangular 6.5‑cup containers combine restaurant‑grade borosilicate glass with silicone‑sealed locking lids so you can cook, chill and carry meals with minimal fuss. The set is designed to save refrigerator space, withstand thermal changes, and move from oven or microwave to table, while the snap‑on lids provide spill protection for everyday use. Lids are BPA‑free plastic with silicone seals; they must be snapped closed in the correct sequence to form a secure airtight seal.

How does this set perform for cooking, reheating and serving?

The borosilicate glass tolerates a wide temperature range so you can bake or reheat safely (check lid compatibility first). Glass gives even heat distribution and a clean presentation for serving directly from the container. Note that the plastic lids are NOT oven or microwave safe — remove lids before applying direct heat.

• Oven and microwave safe for glass pieces; lids should be removed for heat exposure.
• Heat resistant from roughly -40°C to 520°C for safe thermal transitions.
• Clear glass makes contents visible for serving and portion control.
• Rectangle shape fits efficiently in fridge and oven racks.

Are these containers leakproof and airtight for transportation?

The lids use a four‑flap locking system with a silicone gasket to create an airtight, leak‑resistant seal when closed in the correct order. If flaps are misaligned the seal may not form properly, so align and snap one side at a time to ensure no liquid escapes. The design is intended for transporting liquids and saucy dishes short distances.

• Silicone gasket prevents spills and keeps food fresher longer.
• Four‑sided locking flaps provide a secure closure when used correctly.
• Ideal for packed lunches, meal prep and fridge storage.

How should I care for and clean the Razab glass containers?

Borosilicate glass is durable and reusable; wash the glass pieces in warm, soapy water or on the top rack of the dishwasher. Remove and clean the silicone seal and plastic lids separately to avoid warping and to maintain the gasket’s effectiveness. Inspect lids and seals regularly and replace if they show wear to keep airtight performance.

• Dishwasher safe for glass (top rack recommended).
• Hand‑wash lids and silicone seals to prolong life and maintain sealing.
• Check flap alignment and gasket condition before each use.

How much food will each container hold and how does the shape help storage?

Each container holds 52 oz (6.5 cups), a practical size for single meals or family leftovers. The rectangular profile reduces wasted space in refrigerators and on pantry shelves compared with round containers, making stacking and side‑by‑side storage more efficient. The clear glass also helps you identify contents quickly without opening the lid.

• 52 oz (6.5 cups) capacity per container for main dishes or sides.
• Rectangular design maximizes shelf and fridge space utilization.
• Clear glass provides instant visibility for meal rotation and portioning.

Who is this for: This Razab 4‑piece glass set suits home cooks, meal preppers and busy households that want durable, multi‑functional containers that can go from oven or microwave to table and back into the fridge. It’s a good match if you prefer glass for flavor neutrality and easy visibility, want airtight transport for lunches or leftovers, and plan to hand‑wash lids to preserve the silicone seals. Avoid using the plastic lids in the oven or microwave and always follow the proper flap‑closing sequence for a reliable airtight seal.
