How to Wear Fin

Fin’s body is designed to be held between two fingers, 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 way 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.

Charging Fin

Battery life (high intensity/steady mode): 1.5 hours
Charge time: 2 hours

The first time you charge Fin, you’ll 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 indicator is located near the charging port. The LED will blink green when Fin is charging and turn solid when charging is complete.

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.

Travel Mode

In Travel Mode, Fin can’t be turned on accidentally. Hold the button for 10 seconds to activate—the LED will blink the count and flash red at the end. To exit Travel Mode, just plug Fin in to charge.

Caring for Fin

Fin is splash-proof. Always clean Fin after every use, using either a damp cloth or a water-based sex toy cleaner like Dame’s Hand + Vibe Cleaner. Dry thoroughly. Store Fin separately from other toys, and away from extreme heat or cold. You can store Fin in the linen bag provided.


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