The PalmEmbrace is made to fit on a PalmPower Massager or PalmPower Recharge (not included, but we do sell them!). It's made of silicone and designed internal and external pleasure. Our tester found that the specific design of this model was terrific at getting her G-spot and clit simultaneously and it worked equally well when she flipped it around to tickler her backdoor with the outer prong. (The Palm Dual from the PalmPower Sensual Attachments, which has a similar design, was also wonderfully effective in both front and back positions for our tester.)
The insertable prong is just about 3” long and 1-1/4” by a little over 1-1/8” in diameter at the widest point. Of course, as we always mention, bodies vary widely, so we can’t guarantee that the fit for you will be the same as it was for our tester, but why not give it a whirl?
