Many years ago, Achaosofkittens bought me a mug from Goodly Woods at MD Ren Fair. I took it to work, because it reminded me of CK and also because no one would ever be mistaking it for anyone else's mug. While it was at work, the mug got a LOT of use. Years later - this past winter, in fact - it developed a leak down one of the joins.
I contacted the seller, Joseph Victor, through his web page, because the page said that he would attempt repairs. I got back an articulate and friendly note complete with expectations regarding timing and possible pricing. So then I sent the mug out to Joe in New Mexico for a lookover. His response was that it was a warranty issue, and that he would be fixing it and shipping it back at his cost.
I got the mug back yesterday. And it looks new! It's clean, polished, re-sealed, repaired, and did I mention clean? Along with repairing and re-sealing the wood, Joe scrubbed all of the tea stains out. So I got a like-new mug for the cost of one-way shipping.
