## Description

ECOlunchbox Solo Cube | Stainless Steel Food Storage Square Container | 5.25 x 5.25 x 2 inches (13 x 13 x 5 cm) | Holds 2.5 Cups (21 oz, 620ml) of Foods | Durable Metal Bento for Lunches & Snacks

## Features

- SQUARE STAINLESS STEEL BENTO: Built to last from 100% rugged and tested stainless steel, this bento measures 5.25 x 5.25 inches square by 2 inches deep. This versatile, go-to container holds 2.5 cups (21 oz). It's the perfect size for a small sandwich, cut fruit, leftovers or any other foods to-go that aren't too wet.
- NOT LEAKPROOF: The container’s stainless steel lid is easy to use, even for young children. There are no gaskets in this lunchbox’s design, so it’s not appropriate for packing wet foods that might leak. If you’re looking for a leak-proof food container, check out other products by ECOlunchbox, such as our Blue Water Bento Splash Box and Blue Water Bento Seal Cup Trio that have silicone lids.
- 100% PLASTIC FREE, NON BREAKABLE & BPA-FREE: Made from the high-quality, food-safe stainless steel. Steel container is lighter than a comparable glass container and virtually non-breakable. ECOlunchbox stainless steel food containers, which are third party independently tested, are free of estrogen-mimicking toxins commonly found in plastic, such as BPA (bisphenol-A), BPS (bisphenol-S) and phthalates.
- DISHWASHER SAFE: All parts of our stainless steel bento boxes are dishwasher safe, including the lid! No need to hand wash lids separately from the container bases like with other brands with lids made from plastic or with embedded gunky gaskets.
- TRUSTED MISSION-BASED BRAND: California eco mom and environmentalist Sandra Ann Harris designed the original ECOlunchbox stainless steel food container more than 10 years ago to pack lunches for her two young children. The woman-owned company continues as a mission-based, family-owned business dedicated to helping people reduce their dependence on plastics for health and environmental reasons. We stand behind our products and offer a one-year limited warranty against manufacturer’s defects.

## 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. 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.

### ⭐⭐⭐⭐ Good product but lid may be hard for kids to open by themselves
*by M***B on January 31, 2014*

Good product- glad it's stainless steel but cover could be hard to open for toddlers. It's not the easiest even for me to open but I guess that's good so food won't spill. Great for sandwiches and live that it is NOT plastic! :)

### ⭐⭐⭐⭐⭐ Glad I Bought It For My Son
*by M***A on January 3, 2014*

I have a little man who is in Kindergarten and I bought this lunch for him, which is just the right size. It is easy to clean up, easy for him to open, and durable. Worth the buy!
