Ink bottles are containers designed to hold liquid ink, which is used for writing or drawing. They come in various shapes and sizes, often made from glass or plastic. Ink bottles typically have a narrow neck to allow for easy filling of pens or brushes, and some feature a built-in dropper or applicator for precise use. Historically, ink bottles were essential tools for writers and artists, especially before the invention of disposable pens. Many ink bottles are collectible items, showcasing different designs and colors, and they often reflect the styles of the Victorian era or Art Deco period.
