Well, I know that The House of Staunton did carefully inspect each piece of a set before shipping. But that was before 2008. And that was when Frank Camaratta owned the place. I know, from experience, that since then the sets stay in their packaging, on a shelf, from the manufacturer in a warehouse until shipped.
I last bought a set from them in December of 2019. It was their newest Drueke reproduction. It is my experience when a set is newly released, that first batch of sets from them are fine. I have seen and heard from others about piece problems with sets they have offered for quite awhile.
These Zagreb sets come under the category of out for quite awhile. Now, if I would need to buy such a set, I would call and ask for Kevin. I would tell him I wanted to make sure the set I got had a certain graining color or something like that. Then Kevin would go to the warehouse himself and inspect the set.
Of course it should not need to be this way. But it is.
My personal experience with "The House of Staunton" chess pieces
In the course of the last three quarters of a year I have purchased a total number of 11 sets of chess pieces from "The House of Staunton". As they claim on their website in the category CARING FOR YOUR HOUSE OF STAUNTON SOLID WOOD CHESS PRODUCTS , "you can have absolute confidence that the chess products are as close to perfection as can be achieved by human hands." This is what they claim.
Now for my personal experience: I had to find out that in every single set of those 11 ("Zagreb ´59 purpleheart gilded and natural boxwood, 3.75´king" and "Zagreb ´59 rosewood gilded and natural boxwood, 3.75´king") there were several pieces in imperfect condition. When I say "imperfect", I mean specifically, that in every set a number of the pieces had ugly notches in the wood, apparently caused by an imprecisely working hand carver slipping his carving tool. These notches have been (and continue to be) a source of constant annoyance.
The point "Wood is a natural product, so you cannot expect wooden chess pieces to be perfect!" is simply wrong - the counter evidence lies in the fact that some of the pieces were in fact in a flawless condition. It is inconceivable to me, why it is obviously not possible to apply this standard to all pieces of a chess set.
"The House of Staunton" write on their website that their chess pieces "undergo an exhaustive inspection process before packing to insure that they meet our high standards." I don´t know what their "high standard" is, but I can say that it obviously deviates from mine considerably...
Being a perfectionist, I expect a set of valuable chess pieces to be crafted in a flawless condition, from the very first to the very last piece. Full stop.
These requirements have not been met by "The House of Staunton".
All this shows the decisive disadvantage of online-shopping: as a customer you never have the chance to inspect the product before purchasing it, but you have to rely on others. My experience in general - and with "The House of Staunton" in particular - is that this is a very bad idea...
