If you haven't already read about the stupendously powerful Palm Power 240v Massager - head on over and check it out; it's well worth a look! What you're looking at here is a set of two optional massager heads to swap over to when you need some extra focus on your massage. While the dome cap that comes with the Palm Power is very good, we all need some extra TLC.
These two attachments are called the Palm Finger and the Palm Arm. The finger (which is the narrow one) is designed to simulate slightly pinched fingers and to massage hands and fingers during a full body massage. As you can imagine, these magic fingers are more than ready to go to town on more intimate areas of your body. Since they're 100% silicone, you can put them just about anywhere!
The second attachment, the Palm Arm, is designed to massage broader areas like the arms, but can also lend itself to the back, chest, shoulders and of course more intimate areas. Use it as a clitoral stimulator, or let it wander to your perineum for real zing!
Both of these massage heads have two fingers approximately 3cm long, which is a great length for transferring vibrations right to the tips. This has the effect of accentuating and increasing the already furious top speed of the Palm Power, and under certain circumstances can be almost unbearably vigorous!
