This is a prize I won in a co-op quiz, but I'm not going to use it, so I'm putting it up for sale. There's no size listed, so I measured it. It's about 40 cm wide, 25.5 cm long, and 3 mm thick. The material is listed as polyester and polyurethane. The postal rates increased on October 1st, so I'm sorry, but I've had to raise the listing price as well.
