Urban Green Glass Food Storage Containers Set — 6‑Piece White, Silicone‑Framed Lids, Airtight & Microwave‑Safe

These are a six-piece Urban Green glass food storage containers with silicone-framed glass lids that keep meals fresh, plastic-free, and easy to reheat.

Urban Green designed this set to replace single-use plastics and conventional plastic storage with durable borosilicate glass and soft silicone rims. The collection includes a mix of square, round, and rectangular containers in graduated capacities so you can store leftovers, prep meals, or transport packed lunches while avoiding plastic contact with food. Every lid is framed in silicone and features an easy air-venting mechanism to create a secure, leak-resistant seal and safe microwave reheating when the vent is open.

How does the lid keep food airtight and leak resistant?

The silicone frame around each tempered glass lid creates a snug gasket against the glass base for a tight seal, and an integrated air vent allows pressure to escape when reheating. Close and press to lock the vent and the silicone compresses for a reliable barrier that reduces spills during transport.

• Silicone-framed glass lid forms a compressive gasket for an airtight fit.
• Built-in air vent lets steam escape during microwave use (open vent).
• Press-and-lock action simplifies sealing and minimizes leaks.

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

The containers themselves are high-borosilicate glass rated for high heat and safe for microwave, refrigerator, and dishwasher. The lids are semi-tempered glass with silicone frames; lids are microwave-safe only when the air vent is left open and are dishwasher-safe, but do not place lids under direct stovetop flame or broiler heat.

• Borosilicate glass bodies withstand up to 600°F; safe for oven use (lids not recommended for oven).
• Microwave-safe with lid on if air vent remains open to release steam.
• Dishwasher-safe for easy cleanup; keep lids away from direct open flame.

What sizes and shapes are included and how do they suit meal prep?

This 6-piece set blends square, round, and rectangular containers to cover a variety of portions and food types. Sizes range from small snack portions to large meal-size containers, making the set versatile for storing soups, salads, entrees, and prepped ingredients.

How does this set reduce plastic exposure and environmental impact?

Urban Green intentionally uses borosilicate glass and silicone rather than traditional plastic to keep food contact surfaces free of plastic-derived chemicals. The reusable, durable materials lengthen product life and cut down on disposable container waste, supporting a lower-waste kitchen over time.

• 100% plastic-free contact surfaces between food and container.
• Durable glass resists staining and odor retention common in plastics.
• Reusable design lowers single-use container consumption and waste.

It suits people who reheat meals regularly, want dishwasher-safe containers that won’t retain odors, and prefer stackable glass options for refrigerator organization. Choose this set if you want oven-ready borosilicate glass containers paired with plastic-free silicone-framed lids that balance durability, safety, and everyday practicality.
