I bought this item 10 years ago at a Close-out store.
I use it every day for meals as a Trivet that also keeps hot food hot.
It is essentially a small slab of granite that you can heat in your microwave
It gets nice-and warm after 3 minutes in the microwave, and then it slowly releases its heat
Recently, I use it in my Faux Cambro to pre-heat the interior of the ice-chest.
Once I put the PP into the ice-chest, I re-zapped the granite for 3 minutes, and stuck it back on top of all the towels.
Presumably you could keep re-zapping it every 30 minutes or so if you are worried about heat loss
Here's the ironic part. I bought it at Odd-Lots for $4.99 ten years ago.
Today, they are going for $40 bucks or more.
