There’s just something about the Onyx Plug. We can’t quite explain it but the black glass just seems more elegant, similar to a black tuxedo dressing up an otherwise everyday event. We also think it’s just the right size and shape, the Onyx Plug just seems to fit.
It measures approximately 3 3/4 inches in length with an egg shaped head that measures about 2 1/8 inches long. The head of the Plug features a smooth rounded tip that gradually increases in width until it reaches about 1 1/2 inches in diameter at it’s widest.
The head of the Plug then decreases in diameter and connects to the straight neck that measures about 1 1/4 inches in length and 3/4 of an inch in diameter. The neck then connects to a round flat base that measures 1 1/2 inches in diameter.
