Cobalt blue testtube?

[Ninjafossils]

Well my bottle dump keeps extending outward. On my last trip, I seemed to find the remnants of a 20th century science lab as there were microscope slides and other small science bottles everywhere. This one caught my eye in particular. It appears to be a test tube like bottle, cobalt blue, with a screw top. Any additional information you guys can find would be greatly appreciated.

It appears to be a Bourjois brand perfume vial.

nhbenz is correct... I have one with the lid which has a hole on top of it where the string attached.

Bourjois' scent in these was "Evening in Paris", which was introduced in 1928 and retired in 1969... I didn't find out what years they used these "bullet" bottles.
