  • Use it as a dick leash! attach the device just under the glans and adjust pressure with the integrated screws.

  • This Locking Spiked Ball Stretcher will separate and restrain your balls while the adjustable intensity screws provide intense CBT sensation. Each of the screws is topped by a point, designed to twist deeper into your tender flesh with every turn. The barrel is split to open completely, and the arm swings away for easy installment. Just clamp the barrel around the base of your scrotum and attach the arm with the included lock. Now, there is no escape.

  • There is an included Allen wrench to adjust the pressure of each point, 6 total. Use this intense toy to test the limits of what you can take, or remove the screws completely to use as a standard ball stretcher.

  • Your chosen ball weight should be loose and comfortable enough not to restrict blood flow. On the other hand, it should also be tight enough not to allow testicles to slip through.

  • Put the measuring tape around the top of the testicles. It’s important that your both testicles rest comfortably under the tape.

  • For the most accurate measurement, it’s important to perform several measurements and to write down at least 5 results.

  • After you have obtained the measurements, calculate the average value: Use our calculator for this purpose.

  • Multiply this result by 0.74 and 0.8 to get the tightest and loosest size you can wear.

  • Divide each of these results with 3.14 to get the tightest and loosest inner diameter you can wear.

  • Order ball weights with inner diameters between these two sizes.
