How to use this Ball stretching device?

To put it on simply remove the movable part on side as per video. Slide you balls in through the hole opening on this side. Put back the loose part and make it as one with the stretcher.

How to measure your size:

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. For this model, take into account the wide only, 42/45/47mm.
