Ready to take full control of your stretch? The Master Series Custom Ball Stretcher Kit gives you complete freedom to dial in the pressure, tension, and tug you want—on your terms. Whether you’re just starting your stretching journey or pushing deeper into long-term wear, this modular setup adapts to your body and your cravings.

It includes three stackable rings (10mm, 15mm, and 20mm) so you can start slow or go deep. Each ring is made from solid, polished stainless steel and connects with heavy-duty screws for a secure, industrial fit. Add or remove rings to create your perfect stretch length—and once it’s locked on, it’s not going anywhere. This kit isn’t just a toy—it’s gear for men who take their pleasure seriously.
