Here are some pictures of the scrapes and scratches. As you can see, they're pretty minor and only cosmetic. otherwise the inside of the pipe is very clean and the packing is very very very quiet. you can talk into one end and its muffled coming out the other, very very muffled.
sorry that they're a little out of focus, macro mode wont flash on my camera and the room has poor lighting. i can get better pics if anyone wants them.
