What’s this? Found under a bathroom vanity during remodeling—small glass tubes, 2 inches long, filled with liquid. Any ideas?

The Purpose of Vintage Perfume Ampules
One plausible explanation for these mysterious glass tubes is that they are vintage perfume ampules. In the mid-20th century, it was common for perfumes to be sold in small, single-use glass vials. These ampules were designed for convenience, allowing individuals to carry their favorite scents with them without the bulk of a full-sized bottle. The liquid inside the tubes is likely a concentrated fragrance, preserved over the decades by the sealed glass.
The Popularity Among Women: A Handbag Essential
During the mid-20th century, perfume ampules became a popular accessory among women. These small vials were often tucked into handbags, providing a quick and easy way to freshen up on the go. The allure of having a personal scent readily available was a significant draw, and the compact size of the ampules made them a practical choice. For many women, these glass tubes were an essential part of their daily routine, a symbol of elegance and sophistication.
