12 Pack Glass Meal Prep Containers with Airtight Lids - Meal Prep Made

In this review the 12 Pack Glass Meal Prep Containers aims at anyone who wants a durable, versatile set for weekly meal prep, leftovers and packed lunches. The single biggest reason to buy is the combination of multiple sizes and true borosilicate glass construction, which makes it easy to see contents, transfer from freezer to oven or microwave (lids excluded), and avoid plastic taste or chemical leaching. For a household that needs stackable, airtight storage with dishwasher-safe convenience, these containers deliver consistent everyday performance.

Key Features

• 12-piece set: Includes a thoughtful mix of rectangle, square and round containers so you have sizes suited to lunches, larger leftovers and small snacks without needing extras.
• Borosilicate glass: The durable glass resists stains and odors and can move safely between freezer and oven or microwave (remove lids first) for flexible meal prep.
• Airtight locking lids: Each lid has a silicone seal and locking tabs to keep food fresher and reduce spills when carrying meals to work or school.
• Dishwasher safe: Containers clean easily on the top rack and the removable rubber seal makes it simple to wash and reinstall for long-term hygiene.
• Stackable design: Containers nest and stack to save cabinet space and make organized storage easier in a busy kitchen.

Who It's For

These glass meal prep containers are ideal for families or individuals who prepare multiple meals in advance and want a non-plastic storage option that goes from freezer to oven or microwave. The variety of sizes suits portion control, leftovers and packed lunches, and the airtight lids help prevent odors when transporting food.

People who primarily need single-portion plastic containers for lightweight travel or who require lids that are oven-safe should look elsewhere, since the lids are polypropylene and should be removed before baking or high-heat oven use.

Pros & Cons
