Clear glass essence bottles from the EAGLE range with screw-thread necks, made for holding essences, flavours and similar liquids. They have a round body, gently rounded shoulders and a threaded finish at the mouth that takes a screw cap. Two sizes share this design: a larger bottle with a wide mouth and a smaller, slimmer bottle with a narrower mouth. Both are in transparent glass, so the colour and level of the contents stay easy to see.
