A classic gag item, just put it in your mouth, blow and a cool whistling sound is produced. These are great fun to take out on a night out. Handy for when you see someone you fancy and you want to let them know! It's hilarious and is great for using on aeroplanes, elevators, parties, the office, blind dates, weddings, in the classroom, on the street, in the pub etc. One of the best pulling techniques available today! Make sure when you see some totty you are equipped with your wolf whistle!
