Using the Calexotics Lock - n - Play Remote Flicker Panty Teaser is easy. First, attach the teaser to your panties using the magnetic tab wings.

With the remote, you can adjust the vibration intensity and cycle through the 12 functions with just a touch of a button. When you're done using it, make sure to clean it with mild soap and warm water because it's waterproof. Keep it in a cool, dry place. Charge it using the provided USB cable for 1.5 hours when the battery is low. Don't expose it to extreme temperatures or sharp objects. And always follow your personal comfort level when using this toy.
