A small, flat, wedge-form bottle of molded plastic, roughly rectangular in side profile, taller/thicker at the neck end and tapering slightly toward the opposite (far) end, which terminates in a scalloped, ribbed edge. Each broad face carries a central panel of parallel ribbing enclosed in a rounded-end (stadium/teardrop) frame, surrounded by a finely stippled diamond/cross-hatch texture. A short cylindrical neck set at one upper corner carries a ribbed screw cap (apparently, artisanally made to substitute the original). The body is a pale teal/turquoise. No printed or applied label is present on the surfaces shown. One of three near-identical flasks in the collection differing only in color (teal, orange, pink); cataloged as a separate object.
