Our inserts are super soft , hypo-allergenic platinum silicone. They are nicely textured and removable for cleaning after use. The insert nestles right into it's place just past the fixed labia. When placing it back into the body, just apply some baby powder or lubricant so it will slide in easily. It will stay in place when in use. It can also be warmed before use in the microwave or by placing in warm water. Always use water based lubricants.
