This is a 10ml (1/3oz) bottle of olive drab acrylic paint from Tamiya. These handy bottles of paint for hobby use are made from water-soluble acrylic resins and are completely safe. Can be used on most common model plastics such as styrol resin and styrofoam. Paint can be washed away with plain water if done prior to curing. Available in glossy, flat, translucent colors, plus an exclusive thinner and a flat base.
Note: There are two versions of Olive Drab offered in the Tamiya Acrylic Mini series: The TAM81762 XF62 bottle and this TAM81774 XF74. Judging from the color samples offered by Tamiya, it has been observed that the XF62 is slightly browner, where this XF74 is slightly greener.
