Appears to be an end-of-life product. Best price on Amazon is $9.67, also at BBBY for $8. These are on the shelf at Wal-Mart for $3.98.
It’s a real cork outer coating on a plastic coffee cup.
Some selling points:
- Reusable
- Non-slip
- Dishwasher safe
- Anti bacterial
- 16oz capacity
I have no comment as to the quality thus far, I just bought one today.
