Urban Green Glass Food Container Set — 4‑Pack Silicone‑Framed Lids, Leakproof Plastic‑Free Meal Prep

Urban Green 4-pack glass food containers are a plastic-free meal-prep set with silicone-framed glass lids designed to keep food fresh and leak-resistant.

These containers combine high-borosilicate glass bodies with silicone-framed, tempered-glass lids that include an easy air-vent and lock to reduce spills and maintain freshness. The set includes multiple sizes in square, round, and rectangular shapes so you can store everything from leftovers to full meals. All pieces are dishwasher- and refrigerator-safe; lids are microwave-safe when the vent is open. The design prioritizes food safety and fewer plastics in the kitchen.

How do these containers prevent leaks during transport?

The silicone frame around each tempered-glass lid forms a tight seal against the container rim, while the built-in air vent locks down to reduce movement of liquids. Close the lid, press to seat the silicone, then lock the vent to help resist accidental spills. The glass-on-glass contact plus the soft silicone barrier improves stability compared with loose plastic lids.

• Silicone-framed tempered glass lids for a snug seal
• Push-to-seat lid and lockable air vent to minimize splashes
• Multiple shapes and sizes to match different foods and portion needs

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

The borosilicate glass containers tolerate high temperatures and are safe in the oven up to 600°F, refrigerator, and dishwasher. The glass lids are microwave-safe only with the air vent open; do not place lids in the oven or expose glass directly to open flame or stovetop heat. For long-term care, avoid thermal shock by not moving hot glass immediately into cold water.

• Borosilicate glass bodies: oven safe up to 600°F and microwave safe
• Glass lids: microwave safe when vent is open; not oven-safe
• Dishwasher-safe full set for easy cleanup

What sizes and shapes come in the set, and how do they fit into meal prep?

This Urban Green bundle offers three shape options—square, round, and rectangle—each including multiple volume sizes to match portions, batch cooking, or storing sauces. Square and round sets include four graduated sizes for everything from snacks to family meals; the rectangle set is tailored for platters and casseroles. Mixing shapes helps stackability and efficient fridge organization.

• Square sizes: 65oz, 39oz, 20oz (various footprint dimensions)
• Round sizes: 55oz, 30oz, 15oz, 8oz for bowls and soups
• Rectangle sizes: large capacities (up to 87oz) for casseroles and meal trays

How does choosing this set reduce plastic use in the kitchen?

Every component in this Urban Green set is free from plastic: lids are glass with silicone frames and the containers are high-borosilicate glass. Switching to reusable glass reduces disposable plastic waste and limits ongoing exposure to plastic food-contact materials. Durable glass also means fewer replacements over time compared with thin plastic containers.

• 100% plastic-free contact surfaces: glass + silicone
• Durable borosilicate glass for long-term reuse
• Eliminates single-use plastic alternatives for storage and meal prep

Who this set is for: Urban Green’s glass containers suit home cooks, meal-preppers, and families who want leak-resistant storage without plastic. They’re ideal for anyone organizing lunches, freezing prepared meals, or keeping food visible and fresh in the fridge while choosing more sustainable kitchenware. If you prioritize easy cleaning, high-heat durability, and plastic-free food contact, this 4-pack collection is a practical upgrade.
