I also bought another stainless container for comparison purposes- the New Wave Enviro Stainless Steel Food Container, for half the cost. I will review it separately. I cannot comment on how long they will last but can say I am really happy with the Solo cube. The edges are curled on the lid and the container, giving it strength and making it really easy to grip to open. It closes easily and snugly, and it fits a sandwich or bagel perfectly- even the jumbo bagels from Costco. My high schooler loves it because it protects her sandwiches from getting smashed in her backpack, and saves a baggie from being used up daily. The comparison to the cheaper New Wave Enviro Stainless Steel Food Container is hard to gauge, because my other high schooler loves that one despite its slightly larger dimensions and the edges are not curled under, and it is held closed with attached clips. Only time will tell how they hod up, and I will update my reviews over time. Review: Great for pbj - I use this for my sons pbj. It's big enough to fit a full size sandwich. The sandwich seems to stay together well. I can toss it in the dishwasher for easy cleaning. ## Features - Square & Compact, Yet Roomy – Measures approximately 5¼" × 5¼" × 2″ and holds around 2.5 cups (21 oz), perfect for sandwiches, pasta salad, fruits, or leftovers. - Durable 100% Stainless Steel – Made from food-safe, non-toxic stainless steel, it's BPA-, BPS-, and phthalate-free, ensuring longevity and safe usage. - Lightweight & Squish‑Proof – Weighing just 8.5 oz (tare weight), the Solo Cube is both sturdy and lightweight—ideal for daily use or packing into a lunch bag without extra bulk. - Dishwasher-Safe & Plastic-Free – Fully dishwasher-safe without hidden plastics, offering easy clean-up and a completely eco-friendly dining experience. - Not Leak‑Proof, but Versatile – With no gasket, it’s not suitable for saucy or liquid foods—but its simple, secure lid is great for solid meals that don't need airtight sealing. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #103,176 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #775 in Individual Household Food Containers | | Customer Reviews | 4.5 out of 5 stars 57 Reviews | ## Images ![ECOlunchbox Solo Cube Stainless Steel Lunch Container, 21 oz – 5.25" Square - Image 1](https://m.media-amazon.com/images/I/513fzBWV4xL.jpg) ![ECOlunchbox Solo Cube Stainless Steel Lunch Container, 21 oz – 5.25" Square - Image 2](https://m.media-amazon.com/images/I/61oE92lhGDL.jpg) ![ECOlunchbox Solo Cube Stainless Steel Lunch Container, 21 oz – 5.25" Square - Image 3](https://m.media-amazon.com/images/I/615RsnMaGSL.jpg) ![ECOlunchbox Solo Cube Stainless Steel Lunch Container, 21 oz – 5.25" Square - Image 4](https://m.media-amazon.com/images/I/61-KdKMbyRL.jpg) ![ECOlunchbox Solo Cube Stainless Steel Lunch Container, 21 oz – 5.25" Square - Image 5](https://m.media-amazon.com/images/I/41AT3JkfrYL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What material is the Solo Cube made of?** A: It's made entirely from food-grade stainless steel, including the lid, so it's 100% plastic-free! Because there's no plastic, it's free of the estrogen-mimicking chemicals found in plastic containers, including BPA, BPS, and phthalates. **Q: How much food does it hold?** A: 21 oz, or about 2.5 cups. It measures 5¼ inches square by 2 inches deep. The square shape is sized for a standard sandwich, and it's also great for pasta salad, cut fruit, and leftovers. **Q: Is it dishwasher and microwave safe?** A: It's fully dishwasher safe, but as with all stainless steel, it can't be used in a microwave. You can reheat food in an oven or over a campstove instead. **Q: Will it dent, crack, or break?** A: The Solo Cube is rugged and squish-proof. It won't crack or shatter like plastic or glass, so it holds up to daily use and travel. **Q: Who is the Solo Cube best for?** A: Packing sandwiches and snacks for work, picnics, hikes, or travel. The Solo Cube has no gasket, so it's best for dry or firm foods rather than soup or sauce. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent for daily sandwiches. *by P***L on January 12, 2016* I was hesitant to buy due to the high cost, but am glad I bought it.
