The Ball Stretcher Donut Shape 4CM is a 2-piece medical grade 316 stainless steel ball stretcher with a rounded donut-shaped outer profile. Opens at the side & locks with the included Allen key — closes over the scrotum directly. The taller 4cm height adds more contact area against the scrotum & increases the downward pull compared to the 3cm version.
450g of polished stainless steel. Medical grade 316 is non-porous, corrosion-resistant & can be fully sterilised.
This suits anyone looking for a heavier, taller donut-profile ball stretcher with Allen key closure.
Safety: Keep the Allen key accessible at all times. Monitor circulation closely & remove immediately if numbness, skin colour changes, or sharp pain occurs.
