### Standout Features - **100% Plastic-Free Construction:** Crafted from non-toxic 18/8 stainless steel, the containers are free of BPA, BPS, phthalates, and lead. - **Leakproof Silicone Lids:** Flexible silicone lids keep the containers leak-proof, preventing spills and keeping food fresh, while also being easy for small hands to open. - **Space-Saving Nesting Design:** The containers are both stackable and nestable, saving space in your fridge and simplifying organization. - **Versatile Sizing Options:** The round nesting trio includes 5 oz, 9 oz, and 16 oz containers, ideal for various food packing needs from large snacks to small portions. A larger square trio (15 oz, 30 oz, and 50 oz) is also available. - **Etched Tare Weights:** Each container features etched tare weights for easy bulk shopping. - **Freezer & Oven Compatible:** Both the containers and lids are freezer safe, and the metal container (not the lid) is oven safe up to 150°C (300°F).

### Who It's For Shoppers looking for non-plastic storage containers who find glass too heavy or impractical — especially for sending kids to school — will find these a strong fit. They're well-suited for a wide range of uses including school and work lunches, picnics, takeout, travel, outdoor adventures, bulk shopping, and family leftovers. Those already committed to a zero-waste or low-plastic lifestyle will find the nesting format particularly useful for keeping a full set without cluttering cupboards.

### Important Considerations - **Not Microwave Safe:** These containers are not suitable for use in a microwave — a real trade-off if reheating on the go is part of your routine. - **Size Can Surprise:** Some reviewers note the containers are smaller than expected based on the product description, so check the listed dimensions carefully before purchasing. - **Lid Durability Concerns:** At least one long-term customer who purchased the set over 5 years ago noted the newer lids are not as strong as earlier versions. - **Price Point:** The stainless steel feels of good quality and holds up well for nearly daily use, though it's noted as "a little pricey for the size." The round nesting trio retails around $43, which is a higher upfront cost compared to plastic alternatives.
