The Sistema Klip It line is a top pick for microwave-safe food storage because of its patented click-seal lid that locks tight to prevent leaks and splatters. We researched four popular sets to help you choose the right one for meal prep and leftovers.
Sistema Klip It containers are BPA-free, microwave-safe (without lid for heating, lid can be used for venting), dishwasher-safe, and stackable. The seal is designed to be leak-resistant but not fully waterproof for liquids. The plastic is durable but can warp if overheated empty.

Best for: Meal preppers and families who need multiple sizes for leftovers and lunches.

- What we like: Lids seal tightly with a satisfying click. Wide size range. Stackable design saves space. Plastic is sturdy and doesn’t stain easily.

Sistema Klip It Buying Guide
Understanding Sistema Klip It Lids
The signature feature is the four-sided clip lid that snaps down to create a tight seal. This design is leak-resistant but not airtight. For microwave use, you can either leave the lid slightly ajar or remove it entirely to let steam escape. The lid is not intended for full-pressure sealing during heating.
Choosing the Right Sizes
Sistema offers sets ranging from tiny snack cups to large 3.0L containers. For meal prep, the 1.0L and 1.5L sizes are most versatile for single servings. The 0.5L is good for sides or small portions. The 3.0L works for family-sized leftovers. Avoid buying only large sizes if you primarily need individual portions.
Microwave Safety and Care
All Klip It containers are microwave-safe (without lid for heating, lid can be used vented). Do not microwave empty containers as they can warp. They are also freezer-safe and dishwasher-safe (top rack recommended for lids). Over time, lids may absorb odors from strong foods like tomato sauce; hand washing helps.
Safety Notes
- Always vent or remove lid before microwaving to prevent pressure buildup.
- Do not microwave empty containers; they can warp and become uneven.
- Avoid using abrasive scrubbers on lids as they can damage the seal.
- Inspect lids regularly for cracks or warping and replace if damaged.
What to Avoid
- Sistema Klip It 2-Piece Soup Mugs: lids warp in microwave, seal fails for hot liquids.
- Sistema Klip It 4-Piece Rectangle Set: odd sizes that don’t stack well with other containers.
- Sistema Klip It 1.2L Round Container: lid tends to pop off when microwaving thick soups.
- Sistema Klip It 0.8L Square Container: corners are hard to clean and lids crack prematurely.

Final Verdict
