SpareParts Hardwear Harness O-Stabilizer Rings
Great for supporting heavier dildos, or dildos with small or flimsy bases. Expands the size of the dildo base, providing better stability to the dildo when using strap-on harnesses. Simple to use, just wet the inside hole with a little water, and slide down the dildos shaft! Available in two sizes: Small/Med, or Large (for dildos that have a smaller flange on the top).
