Popcorn maker (North Watford WD25)

Joseph Joseph brand microwave popcorn maker. It didn’t get on with our microwave or I didn’t follow the instructions properly and it now has a slightly burnt bit on it. It should still work fine if you know how to use it though. Same one can currently be bought on Amazon: https://www.amazon.co.uk/Joseph-M-Cuisine-Family-Sized-Popcorn/
