Jack Knobber

Sure, they're cute, but do they really work?

Absolutely.

If you have muscular aches and pains, you know just how relieving it is - and how heavenly it feels! - to have pressure applied directly to those knots. Go deep or go gentle, the Jack Knobber massages either way!
The Jack Knobber II's unique ergonomic design lets you massage right through clothing. Or add massage oil and really pamper your skin!
Using this simple device, you can treat your own or another's muscular aches and pains. If you have a serious underlying injury or illness, though, or if pain persists or new symptoms appear, consult your doctor.
