Hey Simon,
Aren't the SW mugs supposed to be Orca coated? maybe too thin a coat? Well, if my customers send them back I'll expect SW to refund every single one at retail price lol. From what i've seen and read SW have made a great effort to improve what was a very poor service in recent months.
LW mugs, if you saw what we'd been sent you'd understand why we don't use them.
