Fin™ (English)

Fin is a vibrator worn between the fingers to provide seamless vibration during intimate moments. 

First Things First

Please fully charge your Fin before use.

Charging Fin

The first time you charge Fin, you will need to puncture the silicone with the provided USB cable. Then plug the USB into any 5V USB power supply, such as a computer or the ones that come with most phones. The LED will blink green when charging and turn solid when charging is complete. Charging Fin from a completely drained battery takes about 2.5 hours.

Fin comes with a rechargeable battery that lasts for about 5 hours of use on the low setting and 75 minutes of use on the high setting.

Once Fin’s battery starts to get low, the LED will blink red. When the battery is completely drained, the LED will blink red once when you press the button.

How to Wear Fin

Fin’s body is designed to be held between two fingers, either with or without its detachable tether.

Its body is asymmetrical, so it feels different on either end. You can rotate it for the sensation you want.


Try sliding Fin along the length of your fingers to find the most comfortable spot to hold it.


To add vibration to your direct touch, you can flip Fin above the hand or slide it to the base of your fingers.

Using Fin

Fin has one button which controls the vibrator settings. Press the button once to use the low setting. Press again to cycle through the medium and high settings. At any point, press and hold the button down to turn the vibrator off.

Travel Mode

Hold the button for 10 seconds to activate - the LED will blink the count and flash red at the end. In Travel Mode, Fin cannot be turned on accidentally. Plug Fin in to exit this mode.

Cleaning Fin

As with any sex toy, cleaning and proper care are very important. Always clean Fin after every use. Fin is made from medical-grade silicone and should be cared for with that in mind.

Ways You Can Clean Fin

  • Anti-bacterial soap and water

  • Anti-bacterial sex toy cleaner

Storing Fin

  • Store in provided satin bag or similar cloth bag

  • Store separately from other toys; sex toys of different materials can damage each other if left in contact

  • Keep away from extreme cold or heat


  • Do not use silicone-based lube with Fin
  • Do not clean with products containing alcohol, petroleum, or acetone
  • Do not boil, bake, microwave, or run through the dishwasher
  • Do not submerge in water; Fin is splash-proof, not waterproof
