DONGER Glass Dildo starts with a softly tapered head then comes two bulbs that are both 1/8" (3mm) larger than the head. These are followed by the largest center bulb which is another 1/8" (3mm) larger and this is the diameter you will select for this sex toy. There is a short shaft which can be textured then a bulb that is 5/8" (16mm) smaller than the selected diameter. Another short shaft follows, again which can be textured, and the tapered head to end the piece will be 1/2" (13mm) smaller than the diameter you chose.

The sex toy length will vary depending upon diameter chosen but dildos range from 9"-11" (225mm-275mm).
