orca coating

[logobear]

I thought it was brown ale, maybe it was sherry......
But always been happy with orca mugs, - to date, think I am on my third pallet in about a year, occasional breaks just replaced no questions.
Never noticed any spots/flat spots etc
I have been offered mugs for a penny or two less, but i prefere a reliable product I know.
I did my first sub mugs 4 years and 1 month ago, and still have a couple in my kitchen in daily use, they are orca, and are definitely dishwasher proof!
