I've heard the chrome-tanned is the bad actor for holsters. Check out http://www.durofelt.com They're in Little Rock; run by an Indian lady who goes home annually to inspect the factory. So it's not American-made but a good product in my estimation. Contact cements outgases for a while but I dont think it would matter in the long term in a vault-size room with air exchange. Latex paint would be worse.
