feels good

Bought a long time ago (I'm quite positive at a thrift store),

it has not been removed from its box or moved from its
storage spot in our upstairs bathroom.

Today, I removed it from the box

and filled it with hot water to sooth an aching leg.
It works.

How good it feels!

Do you have one?

When was the last time you used it?

OK.  Disclaimer. 
When I got up from my chair, I realized my bargain
hot water bottle leaked! 
It looked to me as though it had never been used.
I have NO idea how old it was. 
Maybe the water I used (though not boiling) was too hot?
It felt good while it lasted.
Now it only feels VERY wet.
