Small, clear glass rectangular bottle with straight sides, a short neck, and a threaded top designed for a screw-on cap (now missing). The glass is slightly curved on the front and back panels. There is visible residue and discoloration on the inside of the bottle, indicating prior use or contents that have since evaporated.
This style of bottle was commonly used for medicinal liquids, tinctures, or extracts, but it could also have contained perfumes, oils, or household remedies.
