Oiler cap

The cork is made of a head and a tenon. The head is oval with an almost flat top and is empty. It rests on a cylindrical body, slightly narrowed into a spindle, which is solid. It connects with the tenon, which is solid and slightly tapered towards its base; its surface is frosted. The base shows a trace of unpolished glass pontil; the decoration consists of the air bubble adorning the inside of the stopper head.
