Bassoon Bocal Brush

This bocal interior cleaning brush works fine. However, it has been misrepresented here in the ad. I ordered this one because it shows two brushes with yellow plastic insulation and it claims it won't scratch the Boca's interior. I have previously owned one like this one shown in the photo ad and presumed that's what I'd be getting.What I got was an uninsulated, single cleaning brush attached to a metal coil wrapped around a metal wire. I feel this will risk scratching the bocal's interior plus it's overpriced for what you get - one brush instead of two. It will cost me additional postage to return it so I'm stuck using it as it's not what I expected.
