What to know before buying

  • The listed hot and cold retention times are manufacturer claims, not verified performance guarantees. The description recommends preheating or precooling for 3 minutes. Customer feedback is mixed on how well the jar maintains temperature, so buyers relying on food staying hot or cold should account for that uncertainty.

What’s in the box

Included
  • Stainless steel folding spoon

Who is it for?

A good fit for

Less suited to
