Two more rings for your balls

Two stackable ball stretcher rings in stretchy TPR, made to add to the Sport Fucker Boner Kit. Stack them at the top of your sack, above your balls, for a longer stretch and a heavier hang.

Best forBoner Kit owners who want more length in the stretch on their balls.

Saturday laundry, and all you're wearing is the stack of rings around your balls. Every towel you fold comes with a slow, heavy sway, and the guy you're texting asks for a photo. Of the folding, obviously.

  • Rounded-square donuts: thick, glossy and smooth, with nothing to catch
  • Stretches wide to go over your balls, then snaps back firm and snug
  • This pack plus the Boner Kit gives you four rings; every one you add lengthens the stretch
  • Black or clear, to match your kit or deliberately clash with it

Stackable ball stretcher ring size guide

Stretchy, one size. Each ring is about 0.9 in (23 mm) square on the inside and 1.3 in square on the outside at rest, and the TPR gives a long way to get over your balls. They're made to sit at the top of your sack rather than around your cock; if a full stack sounds like a lot, start with one ring, or ask Adam in the chat.

How to stack ball stretcher rings

  1. Start soft, with a little water-based lube on your balls and inside the rings.
  2. Stretch one ring open, ease your balls through one at a time and let it settle at the top of your sack.
  3. Add the next ring the same way, right below the first. To take them off, start with the lowest and work upward.

Care

Wash before and after each use, pat dry with a soft cotton towel and let it air dry completely. Store away from other toys, heat and sunlight.

SafetyTake it off after about 30 minutes, and right away if you feel numbness, coldness or pain.
