MultiUse offers personalized key rings in different colors, shapes and with optional text. All models work like regular key rings, but they differ in function. The MultiUse Combo is our most advanced model and works as both a shopping cart opener and a can opener, while our other models – including heart, rectangular and Hello-Kitty shapes – work as can openers. We also have a secret student product that will be launched later. For those of you who want to create something completely unique, we also offer the opportunity to design your own product where you choose the shape and function according to your own ideas.
