Rectangular blue enamelled glass canteen encased in a stitched wool or felt cover, reinforced with two horizontal leather straps and metal rings for carrying. The cap is metallic, possibly nickel-plated or tin, attached to the bottle neck by a short cord. The outer wool covering shows significant wear, with holes revealing the blue enamel beneath.
The leather straps are dark brown and heavily aged, secured by green-patinated brass rings. The overall construction suggests a military field-issue canteen, typical of early 20th-century European or Commonwealth forces.
