This is an absolutely true statement
"We also spoke with Skip Ritchie and was informed that there was a problem with the acrylic used in one batch which he was unaware of at the time and the chemical issues did not develop until after he had shipped our order."
Absolutely true. I have worked with vegetable tanned leather for many years.
Leather is an organic natural material & sometimes odd things just happen.
It's also very possible for an error in the initial tanning process to affect the leather finish way on down down the road or for trace residual tanning compounds to chemically react with a final finish.
It would be impossible for the maker to know that there was any sort of problem beforehand and before the cosmetic defect or defects actually occurred.
That would be unless the maker finished his leather goods and then just shelved them for a month (or so) before shipping them out and that sure would not make his/her customers too very happy.
Also unless the holster maker was also a chemist with an analytical lab at his disposal it would be impossible for the maker to know that any specific batch of an acrylic finish was acting problematic.
The important thing is that either the maker or the distributer rectify the situation and make things right in a reasonable amount of time and without any hassle.
It sure sounds like that was done and I don't know that anybody could expect any more than that from either the maker or distributor.
These days finding a MAKER or distributor so ready, willing, & able to make any problem right would (to me) be a reason to keep that maker on my list of GOOD holster makers and suppliers....rather than cross them off.
Just my own personal logical educated opinion.
