This set includes two attachments that specifically fit the Palm Power Jenga or Recharge wand vibrators. These Caps come standard with the vibrators, but intensive use can wear the caps out. So now you can order a new set and keep getting the most out of your Palm Power vibrator. The body-safe silicone material feels incredibly comfortable. Simply attach them to your vibrator and clean them after use with lukewarm water and a toy cleaner.
