This is a very uniquely shaped and thick curved shaft. The shaft is 7 inches in length and varies from 1 1/4 to 1 1/2 inches in diameter. It's multi-colored and has an interesting spiral pattern that runs around the shaft from base to tip. This is a very thick and heavy solid piece of Pyrex that has a clear solid flared base and is designed to stand up. It's available in several color variations: Blue Variation, Black and White and Green or Black. The colors will vary from piece to piece and although the black looks as if it is solid black it does have a more subtle spiral pattern of darker colors as seen in the other styles. When inserted, the thick and heavy nature of this piece will make your partner feel very full in comparison to other thinner dildos.
