1.0 out of 5 stars Can’t get odors out of the silicone This is a nice lunch box but the silicone top liner picks up all the food’s odors and it’s impossible to get out! I’ve tried dish soap with hot water, soaking it with vinegar, rubbing with baking soda paste. Nothing gets the smell out! Very disappointed and wondering if I should send it backVariation: Color: Green
4.0 out of 5 stars Straightforward and Functional Love it. Bought two. One pink and one purple for my kids ages 4 & 6. Easy for them to open and fairly light to carry even stocked with food. Fits inside their Pottery Barn Kids Cold Pack lunch box and there’s still room on top for flat ice pack, utensils, snack and napkin. Note: does NOT fit in their Pottery Barn Kids Classic lunch box. See pics. Easy to clean. I can fit a whole sandwich in these big compartment or a crushable and then some fruit or pretzels in these rubber rectangle thing. No, you can’t microwave this lunchbox obviously but I’m not heating stuff up in these. This is for kids school lunch and sometimes for kids snack take along for beach weekends. It’s a little plain looking to me but my girls love it because they can put stickers all over it. They actually thought that is why the lunchbox arrived so plain/bare LOL It was a little pricey I think for what you’re getting given that there are no bells and whistles just a straightforward solid lunchbox, but I’m still happy with the purchase and it has become our go-to. Hope this review helps!Variation: Color: Purple

5.0 out of 5 stars Great bento box for kids! This lunch box is exactly what we needed. The stainless steel feels sturdy and durable, and the 3-compartment design keeps food separated so flavors don’t mix. Love that it comes with the silicone container for extra flexibility.

Highly recommend for school or travel!Variation: Color: Pink
5.0 out of 5 stars Very good quality, and fits a lot! After trying out several different stainless steel lunchboxes, this is the brand I ended up buying for all my kids! They are very sturdy, they don’t take up unnecessary space besides the food compartment space (no wide gaps between compartments, etc) the lid is easy to open and close (no careful lining it up) and latches well (while still easy for kids to open).They are dishwasher safe, come with an extra silicone divider container, and has plenty of compartment space for a full sized lunch!Oh, and fits an actual sandwich!Variation: Color: Blue
