Your second image didn’t upload properly, could you try reuploading it so I can see what you mean?
I may have misspoken, I was more referring to a colorless frosted glass bottle when I was speaking about a “clear opaque” container.
These sites might have something you’re looking for domestically. Easier customer support, and you can likely get answers on what the glass material is by calling or emailing them, rather than needing to get samples. For orders <5k-10k units I prefer to stay stateside since the economics don’t really shift into China’s favor when you add the cost of sea freight, customs clearance + brokers, and LTL freight to your door.
FWIW, I saw a lot of “ultraviolet glass” that seemed to fit your bill, but it could’ve been a dark blue rather than a black. I just googled “black glass jars”.

Edit: Oops included links to jars rather than dropper bottles hahaha. Thanks @pangea for the good link.
