How big is it, really?
Everything below is drawn to the same scale. Exact measurements for this product are in the description further down the page.
- Insertable length is the part that actually goes in. Total length includes the base, so it always reads longer.
- Girth matters more than length for comfort. If a toy feels like a lot, it is usually the width, not the inches.
- New to this? Start below 6 inches insertable, go slowly, and use plenty of water-based lube.
