I was a little thrown off when I got it. Maybe I was expecting something with more weight on it. It's hallow thinish plastic. The " barb wire" is string. It looks pretty cool but I had to get a glue gun and fix the " barb wire" into place. It was sliding all over the bat and gathering at the base. With some help of a glue gun it made it better. I didn't like the big globs of hot glue it had gathered on the bottom at assembly. I had to take some of the string to hide the huge globs of glue. It' slight weight which is great, the design is cool, it just needed some better assembly work.
