Master Series Ball Stack Ball Stretcher – Clear

The Master Series Ball Stack is a soft ball stretcher made of clear, stretchy TPE in a stack of ridged rings. It slips over the scrotum above the testicles and holds them gently away from the body, giving a light, constant tug. Rows of small nubs at both openings add texture where it touches the skin. It's an easy-going starting point for ball stretching, built for comfort rather than heavy weight or pain.

What a ball stretcher does

A ball stretcher sits around the neck of the scrotum and lengthens it slightly. People enjoy the sense of weight and pull, the extra sensitivity it can bring, and the look. With a soft one like this, the sensation is a gentle pressure rather than a strong drag. It's also something you can wear while moving between positions, because it flexes rather than digging in. Our article on what a ball stretcher does explains the basics in more detail.

Size and fit

The Ball Stack is 1.9 inches tall and 1.9 inches across, with an unstretched inner opening of 0.94 inches. TPE stretches a lot, so that opening widens to pass the testicles and then closes back around the neck of the scrotum. The 1.9-inch height decides how much stretch you get: that's a moderate amount, suited to beginners and people who want to wear one for a while.

Putting it on

Do this when soft and warm; a warm shower first helps. Lube the inside of the stretcher and your skin. Stretch the opening wide with your fingers, ease one testicle through, then the other, and let the stretcher settle above them. Check that no skin is pinched and that the pull feels even. Taking it off is the reverse: lube again, stretch, and ease each side out.

Comfort and time limits

Start with 10 to 15 minutes and increase gradually if all feels well. Remove it at once if you feel sharp pain, numbness, coldness or see a dark colour change. Never sleep in it. Because TPE is soft, it's easy to forget you're wearing it, so set a timer.

The nubs at each opening are small and rounded. On the top edge they press lightly against the base of the shaft; on the lower edge they sit against the testicles. During sex or masturbation they add a little extra sensation each time the body moves, and a partner's hand or mouth will find them too.

Who the Ball Stack suits, and who should look elsewhere

It suits first-time ball stretching and anyone who wants a soft, flexible piece for longer play. If you already know you want more length or weight, a firmer silicone or steel design from our ball stretchers will give a stronger pull. If you'd like to try a few sizes, the XR Ring Master ball stretcher kit offers a range in the same clear look.

Lube, cleaning and storage

Use water-based lube and avoid petroleum products, which Master Series warns against with TPE. Wash in warm water with mild soap, rinse, spray with toy cleaner and let it air dry completely. TPE is slightly porous, so dry it well and keep it in its own bag away from coloured toys, which can stain clear material.
