This is a visually stunning, and beautifully textured double ended glass dildo perfect for vaginal use. It lacks a flare of any sort, or a base to make it truly safe for anal penetration. It doesn't curve at all, so it may seem a little harsh to some. But the fairly dainty girth should make it comfortable for most. As with all glass toys, some care should be taken with how vigorous you are, especially if a partner is using it on you, since that could result with some unpleasant bruising! If trying to use it as a more traditional double ended dildo, the length will be problematic, since it is almost exactly 9" long, it won't quite reach properly.
