They're sealed with shiny red ribbon at the twists and every single cracker hides a gift, hat, snap, and a silly joke inside. These are sold as a bulk pack of 50 (so plenty for large family gatherings!). Each one is 55mm x 55mm x 31cm - they might differ ever so slightly from the image or dimensions. It's definitely worth mentioning they're not really suitable for kids under 3 years old due to little pieces inside.
