### ⭐⭐⭐⭐⭐ 







  
  
    Once you try these you will love them!
  

*by S***L on Reviewed in the United States on January 20, 2018*

Highly recommended- I love these Blue Bento Seal Cups!  I have multiple rounds in just about every size and also a few rectangular ones.  I take my lunch in them to work every day.  I have never had one leak and I do not need to worry about breakage.  Not being able to microwave them is a small drawback, but I mostly use them for salads, cereal, snacks, etc.  They wash up great in the dishwasher and I've never detected any odors retained by the covers, unlike some other silicon items I have used like instant pot seals.  I am buying another one in the extra-large size to take with me for restaurant leftovers as I HATE styrofoam.  Since you cannot see in them (obviously!) I use blue low-tack masking tape and a permanent marker to label them with the contents in the fridge. Once I started using these I pretty much ditched my old plastic containers. I would recommend starting out by trying one, or the round set,  to see what sizes you use most.

Love this container. Also have the smaller set of 3. Haven’t had any issues with leaking and keeps food fresh!

    I love all of their products
  

*by R***N on Reviewed in the United States on May 18, 2018*

I love all of their products. I love the rubber lid - so it flexes a little, and I haven't had any issues with the seal at all. Be patient peeling off the label, and use some hot water and soap.
