Hey guys! I'm not sure whether anyone has ever brought this topic up before (if so, I'm sorry). I ordered J. Herbin inks in two batches, both from different retailers, and my local retailer sent me bottles with plastic caps on them whereas the one in the Netherlands sent ones with metal caps (and they had stickers on the back with serial numbers, the ones from my local retailer didn't). So I was wondering whether J. Herbin made this change (a few years back maybe? because I suspect the ones I got locally are old stock). Thank you in advance
