**Q: Can they be used in a convection oven?**
A: Thank you for the question. The containers are not rated for oven use.

A: Yes! A small to medium sized apple does fit due to the dome shaped lid.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Far better than tupperware
  

*by •***• on Reviewed in the United States on September 30, 2020*

PROS:*Perfect lunch size (see pics scaled to cup noodle container)*Lids easy to clip on/off*Easy to clean*Lid is clear see through*Price point is UNBEATABLE for stainless steelCONS:*Lid seal easily comes off (but easy to slip back on). Which, if lost, the lid would be rendered useless*Stainless steel isn't super thick but sturdy enough for the jobThe pros far outweigh the cons. Especially because no matter how you look at it, this is always a better alternative to cheap, wasteful, unhealthy plastic!!!Take care of them and they'll last a long time I imagineI recommend only hand washing. Takes 2 seconds.

    Great size, seals well
  

*by S***Y on Reviewed in the United States on February 17, 2018*

These containers are really nice, especially for the price. They are a good size for packing snack for kids to take to go and nice and light. The top so far has sealed really well because there is a rubber ring around the outside. The only thing that kept me from 5 stars is that because there is a rubber ring to keep it from leaking, you have to line the top up carefully to get the clips to latch on. But, overall, I’m happy with these and would recommend them for sure

    The size of these containers is perfect for kids lunches
  

*by J***O on Reviewed in the United States on November 21, 2016*

I got these for my 5 year old daughter for lunches.  The type with the press on lids seem to be really hard for her to get on/off by herself.  I bought these because I was hoping the lids would 1. be easier to get on/off by herself and 2. be leak-proof.  The size of these containers is perfect for kids lunches.  I've used it for yogurt and fruit so far.  While it is a bit easier for her to get the lids on and off, they are not leak-proof.  They are okay for thicker yogurts but fruit juice definitely finds a way to escape.  I tested one container by filling with water and holding it sideways with the lid on (like it is stored in her lunchbox).  There was a definite drip, drip, drip of water leaking out.  So, while I'll use these for lunches still, I have to use the hard to manage lidded containers for anything liquid.
