This is an official piece of merchandise, licenced by Valve and made by the now defunct Think geek. It is a foam replica of the Engineer's wrench from the video game Team Fortress 2. These have not been made since 2013/2014, which is when it was purchased. The foam is sturdy and can take a small beating, but I would advise not hitting on things too hard as it can leave dents on the faces of the foam. *Unfortunately I can only extend international shipping to Europe, as I'm dramatically overcharged for anywhere else*
