## Description

EcolunchboxSeal Cup Trio 3-Piece Nesting Stainless Steel Leak-Proof Food Storage Containers

## Features

- NESTING 3-PIECE PLASTIC-FREE, LUNCH CONTAINER SET: Plastic-free and leak-proof, the Seal Cup Trio is three-piece nesting food container set made from 18/8 stainless steel topped with silicone lids. All together, the three containers have a total capacity of 40 oz. (5 cups). The Seal Cup Large container (orange lid) capacity is 20 oz. (2.5 cups). The Seal Cup Medium container (blue lid) capacity is 12 oz. (1.5 cups). The Seal Cup Small (teal lid) capacity is 7 oz.
- NESTS & STACKS: Container nests and stacks one inside the other for compact storage in your cupboard. Real Simple Magazine selected the Blue Water Bento container collection as the best eco-friendly bentos for compact storage. Each container features an embossed ocean motif on its colorful lid. The ocean designs celebrate ECOlunchbox’s mission to make your lunches greener and keeps our oceans bluer by eliminating dangerous plastics from lunchtime.
- 100% PLASTIC FREE, NON BREAKABLE & BPA-FREE: Made from the highest quality 18/8 stainless steel and silicone components.

Our stainless steel food containers are third party independently tested for food safety compliance with USA and EU standards.
- DISHWASHER SAFE: All parts of our metal and silicone bento boxes are dishwasher safe, including the lid! No need to hand wash silicone 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

### ⭐⭐⭐⭐⭐ Leakproof!
*by S***Y on October 12, 2019*

Yes, these are it! These really are leakproof!!! Filled one with water and shook several times and not a drop came out. Nicely lightweight - about the weight of store-brand tupperware containers. Had bought two other varieties of SS containers and both had raw exposed edges and these ones have nice, rolled edges with no raw material showing through. Excellent design and I feel safe to store my toddler's food in them.Edit: Have used these almost daily for the last few weeks and so far no complaints. They indeed are leakproof. Noticed a metallic taste to greek yogurt after storing for maybe two hours, but perhaps that is to be expected given that acidic foods will acquire a metallic taste from stainless steel.Edit 2: Now almost a year after purchasing and daily use, I have not had the metallic taste reoccur after that first time, despite still storing frozen blueberries or raspberries with yogurt all the time (a rather acidic mixture). My toddler has dropped these many times and they are still perfectly dent-less. And I've never had a leak. I am now buying a second set because we use these so much. I have also become much more savvy about SS products, and love that these are a very high grade of stainless steel (i.e. will not rust).

### ⭐⭐⭐⭐⭐ My new favorite containers!
*by R***Y on April 25, 2016*

These are seriously the BEST containers I have ever used. I love that the lids are silicone, not plastic. I avoid plastic when it comes to food, but I also like the silicone because it you pack slightly more than the size of the containers, the lid will still conform to the containers, with just a small bump across the top. These containers are leakproof as advertised. I have ran them through my dishwasher several times and I have had no issues. I have not used any of the pieces in the oven so I can't say anything about that part. The containers are spacious. If you see the picture grid I added, you can see that the smallest container easily holds the segments of THREE Mandarin oranges with room to spare. If you look closely at the picture grid, you can see that I slightly overfilled the medium container and you can see what I mean about the silicone lid conforming to the shape. In the picture grid, I sliced an entire Bell pepper into the largest container, and there is room to spare! These containers hold a lot and I continue to be impressed with them. I have used other products by this company and so far, this is definitely my favorite.I received a free set in exchange for my honest opinion about it.

### ⭐⭐⭐⭐⭐ perfect for school lunch
*by P***L on December 21, 2018*

These containers are perfect for my 5 year old's school lunch. The lids are easy for her to take off and put back on by herself (the lids on many of the other leakproof containers are too hard for young kids to use by themselves). I haven't used them for anything super liquidy (mainly Greek yogurt, berries, cut pineapple, and sandwiches), but we've never had any leaks. I did fill them with water to see if they leaked (they didn't). They didn't even leak when the lid wasn't completely pushed all the way down. To be honest, I haven't used the medium or large containers yet. Since my daughter is only 5 and doesn't eat that much, the small size works best. I'm sure we'll use the other containers when she's older and eats more. I do wish they offered the multi size set in rectangle shaped containers instead of round. The rectangle shape fits better in lunch boxes when you're also trying to fit a water bottle and possibly a second container.
