Ever wondered what a killer drink would look like? We say, it would look as though it came from this cup – the Arsenic Mug. Being a killer element in its own right, this £6.99 mug is the perfect one to have at the office pantry if you want to freak the rest of your colleagues out. Just serve the boss you most despise tea with this mug, and see him look at you suspiciously before he tries to secretly pour the tea into the nearest plant’s pot. Here’s to good health and long life!
