Urban Green Glass Food Storage Containers 4-Pack Rectangular Borosilicate Set with Silicone-Framed Airtight Lids

These are a four-piece set of Urban Green borosilicate glass food storage containers with silicone-framed glass lids that provide airtight, plastic-free storage for meal prep and leftovers.

Urban Green’s glass container collection is built for people who want durable, transparent storage without plastic contact. Each rectangular container is made from tempered borosilicate glass and pairs with a silicone-framed glass lid that seals via an air-vent lock. The set covers common portion sizes and is designed to move safely between freezer, microwave (with vent open), dishwasher, and oven (container only), making it a flexible choice for everyday kitchen organization.

How do these containers prevent leaks when you’re on the go?

The lids use a silicone frame and a locking air-vent mechanism to create a tight seal around the glass rim. Close the lid, press it down, and engage the vent-lock to reduce spills and keep sauces contained during transport.

• Silicone-framed glass lids for a snug gasket seal
• Air-vent lock to equalize pressure and stop leaks
• Rectangular shape reduces shifting in bags or lunchboxes
• Tempered glass resists deformation over time

Are these safe for cooking, reheating, and cold storage?

The borosilicate glass containers tolerate wide temperature changes and are safe for refrigerator, freezer, microwave (leave vent open), and oven use (remove lid before oven use). The glass lid can be microwaved with the vent open but is not intended for oven temperatures.

• Freezer-to-oven capable glass body
• Microwave-safe with vent left open on lid
• Glass lid withstands microwave heat; not oven-rated
• Dishwasher-safe parts for easy cleanup

How do the sizes and shapes support meal prep and storage?

The set includes four rectangular containers in graduated capacities to fit entrees, sides, and snacks while maximizing pantry or fridge shelf space. Transparent walls make contents visible so you can quickly find meals and track freshness without opening lids.

• Set includes 50oz, 35oz, 21oz, and 12oz containers
• Rectangular design stacks neatly to save shelf space
• Clear glass walls show contents at a glance
• Versatile sizes for single meals, batch cooking, and leftovers

What makes this set a plastic-free option for everyday use?

Urban Green minimizes plastic contact by using borosilicate glass for the container bodies and tempered glass for the lids, combined with premium silicone framing rather than hard plastics. This reduces direct food contact with synthetic plastics while keeping the practical benefits of a secure, flexible seal.

• Borosilicate glass containers avoid BPA or plastic liners
• Tempered glass lids framed in silicone for durability
• Silicone components are removable and dishwasher-safe
• Designed to reduce microplastic exposure from storageware

Who is this for? This Urban Green 4-pack suits anyone who cooks regularly and wants long-lasting, clear storage without plastic contact—home cooks who batch-cook, people packing school or work meals, and households seeking durable, stackable containers that move easily from freezer to microwave or oven-safe glass. It’s particularly helpful for buyers who value visible organization, airtight seals for transport, and materials built to withstand everyday temperature changes.
