A commemorative set with the Borussia Dortmund logo. I purchased this at the official shop at Signal Iduna Park, Dortmund's home stadium, about 10 years ago, but I've never opened it, so I'm putting it up for sale. The contents include a key, a pen, and two other items that I couldn't identify, and there was no explanation. I did a little searching online, but I couldn't find this product, so I think it's a rather rare item. The key is especially cute, so I recommend it to Dortmund fans.
