- Brand: Butterfly - Series: OUTER FORCE CAF - Grip: AN - Condition: Near Mint 83.61g Used for approximately 30-40 minutes, so there are no dents or wood peeling. There are some slight traces of adhesive. This is the most subdued racket in the Outer Force series, but it bounces better than the Inner Force series. It feels like a wood racket that flies. It's a good racket, but the feel on the forehand doesn't suit me, so I'm selling it.
