Meal Prep Containers 12 oz Round 300 Sets - Airtight Stackable

In this review the Klex 12 oz meal prep containers are examined for small-batch meal prep, catering kitchens, and event catering where bulk portioning matters. The bottom line is simple: this 300-set pack delivers a practical, space-saving solution for storing single servings with a secure seal, making it a strong choice for anyone who needs many identical containers at once. The review focuses on build quality, portion size, and everyday usability for reheating, freezing and stacking.

Key Features

• Perfect size: The 12 oz round shape provides a consistent single-serving portion that works well for snacks, sides, and two smaller servings.
• BPA free & reusable: Made from food grade PP material so containers are durable and intended to be reused up to about 20 times under normal use.
• Leakproof lids: Tight-fitting clear lids help prevent leaks and spills, which aids transport and keeps contents fresh.
• Temperature safe: Rated to withstand temperatures from 14F to 428F (-10C to 220C), so they can be moved between freezer, microwave and dishwasher safely.
• Stackable design: The round containers stack neatly to save storage space in cupboards and commercial kitchens.
• Bulk value: Includes 300 black bases with clear lids, making it convenient for meal prep, catering, or food service use.

Who It's For

The set suits home cooks who prepare weekly meals, small caterers, and businesses that need uniform disposable-reusable packaging for deliveries or events. The 12 oz capacity is ideal for portion control, meal sides, desserts, and leftovers, and the stackable design helps when storage space is limited.

Those who should look elsewhere include buyers who want long-term single-item containers for everyday dishwasher cycles beyond the stated reuse guidance, or shoppers who need a variety pack of sizes rather than 300 identical 12 oz sets. If glass containers or a higher-end lid locking system are required, a different product may be a better fit.

Pros & Cons

Pros

Cons

• All units are the same 12 oz size, so buyers needing multiple portion sizes must purchase additional sets.
