There's nothing worse than eating half a bag of crisps and realising that you haven't got a clip on hand so you can save the rest for later.
Usually, this means you either a) have to eat all of the crisps and feel bad about it or b) roll the packet, put them in your bag and hope that they don't spill out and cause a crumb catastrophe during the course of the day.
Luckily for you, there's now a third option and the simplicity of it all has blown our minds...
To seal a bag of crisps, simply roll the top of the crisp packet a few times, fold in the corners, and then - like some kind of origami ninja - fold the rolled down area in the opposite direction, so it folds over the top of the packet.
This creates a super secure way to seal your crisps and keep them fresh when you're on-the-go.
