Using this Fifty Shades of Grey Sensational Finger Vibrator is easy. First, charge it using the included USB cable. Once charged, simply slide it onto your finger. You can start with a slow speed and gradually increase it to find the most comfortable setting. Whether you're using it on your own or with a partner, apply some water - based lubricant for a more pleasurable experience. When you're done, turn it off and clean it with mild soap and warm water. Make sure it's completely dry before storing it in the provided REPREVE fabric storage bag. Remember, this vibrator is only for external use and should never be used anally.
