SpareParts Stabilizer Ring is 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 a strap-on harness.
Simple to use, just wet the inside of the hole with a little water and slide down the dildo shaft. You can also try the plastic bag method (watch the video below)
Available in two sizes: Small/medium or Large (for dildos, that have a smaller flange on the top).
