I don't think these are 2 dram vials. To me, they look like half-drams. They are commonly used for small amounts of chemicals, biological samples, sediments etc, typically found in science supplies rather than perfumeries. Here are some I found at the museum where I work (sorry for the yardstick being in metrics):

I have some older ones, but they have a grey rubber plug-type stop, not the press on white plastic.
Here's a source for glass vials in various dram sizes with white plastic stops: https://www.emsdiasum.com/microscopy/products/preparation/vials.aspx
Good lead. I think I was looking at that website but I couldn't make the photos bigger. Im curious about the ones labeled "tooled neck". I will hunt around to see if I can order from someone in smaller quantities.
