I’ve never heard of such a thing-I can’t picture wood shrinking like that in a controlled environment, and I can’t see stain as a solid object-but that is just my take-it sounds like a manufacturing screw up to me.
If I were you-get the touch up matching stain, find a place to test it on the inside of one of the doors, a side that is not visible, or a shelf. Be sure to let it dry completely between coats-if more than one is required-and to dry for 24 hours before you pronounce judgment on the match. If you are unhappy, go to plan “B”, and make the manufacturer aware that they have an unhappy lawyer for a customer...
Mr B is a professional, he’s touching up, not us, and he will know how to do it, he’s been in business for 40 years.
i just emailed Mr B to say that in his conversation with the manufacturer’s rep it may not hurt to let her know that we are two lawyers. i said we are not litigious and have never sued a soul for anything, but that it is sometimes helpful for people we are dealing with to know that we know our rights and we know exactly what to do if we are not made whole. being required to pay for the labor of replacement, and potentially being left with doors that do match, do NOT equate to being made whole and that is what is not sitting well right now.
