## Description

Thermos Food Jar with Microwavable Container 12-Ounce Stainless Steel

Review: Perfect, effective, the perfect size. - The Thermos Food Jar with Microwavable Container is a total lifesaver for busy moms. It keeps food warm for hours, perfect for packing lunches that stay fresh until lunchtime. I love that it has a microwavable inner container—no need to dirty extra dishes, just pop it in the microwave when needed. The 12-ounce size is great for kids’ meals or snacks, fitting easily in lunch bags. Plus, the stainless steel is tough enough to handle a few bumps in the backpack. It’s my go-to for sending soups, pasta, or even leftovers, knowing they’ll stay at the right temperature all day.
Review: Great For Make-Ahead Breakfast or Lunch - I use this thermos every day to send my two kids to daycare with warm food for either lunch or breakfast. When sending breakfast items, I don't even bother warming up the outer shell using hot water and it manages to keep the food piping hot for the hour time between preparation and consumption. I've confirmed with the daycare teachers that lunches are still warm when pre-heating the container with hot water and that time difference is 3-4 hours. The only negative experiences I've had with this thermos so far are as follows: 1) One of my kids broke my wife's foot by dropping a full thermos from a high chair. Clearly this product is robust and you may want to consider wearing steel toed boots if you plan on giving the product to a child in an elevated position who doesn't have complete mastery of motor skills. 2) My kids managed to crack the handle tabs of the plastic insert. I've fixed this issue with superglue without issue twice and in the case where I couldn't find the tab piece, I was able to order new plastic insert replacements for $5 each. 3) Daycare lost one of my thermoses and I had to order a new one.

## Questions & Answers

**Q: What's the trick to getting the inner plastic insert out?  It's in tight and I've tried turning counter clockwise and pulling straight up, to no avail**
A: You have to.look inside around the border you will see that there is a little peg type system on both sides that yiu have to match up.in order to open. So you are basically twisting until the pegs are free and then pulling up.

**Q: Is this okay for heating up soup?**
A: If you mean to heat in microwave then yes. NOTE you must remove the plastic container from the metal thermos and remove the cap on the container before placing in microwave. Instructions state that pitting can occur on container when heating tomato or high salt items. I heat it up slowly to try to avoid the pitting.

**Q: so I bought 2 of these but both of the plastic containers broke. Is there anyway to order more plastic containers.**
A: Yes, call Thermos and order directly from them. The shipping is a flat rate, so order a few more for just in case.

**Q: How wide is the mouth?**
A: The mouth opening is 3 1/4 in.wide.

### ⭐⭐⭐⭐ Good but a bit small
*by S***2 on May 13, 2015*

This is a good thermos. It is a bit small for my 9-year-old. It holds just enough for her right now, but I think I will have to buy a larger size soon. Also, there's not enough space to stir the food. So, while it's nice that there's a removable microwavable inner container, I have to microwave it in a separate bowl anyway.
