This is a real potato chip bag shrunken down to fit as a bracelet. Its been melted to the point where it feels like thick plastic in the oven. We used to shrink potato chip packets and make keychains when we were kids, much to mums dismay as her oven trays were left melted sticky messes.
Unfortunately chip packets no longer melt down as effectively but they are still loads of fun to mess around with.
This potato chip packet bracelet comes with complete instructions.
