This is a great harness accessory for supporting heavier dildos, or dildos that have small or flimsy bases.
The O-stabilizer expands the size of the dildo base, providing better stability to the dildo when using strap-on harnesses.
To use, just wet the inside hole with a little water, and slide down the dildo's shaft!
Large size: 3.5" w x 4.125" h with 1.25" center hole
