Hello, Jose. Thanks, for the review. We trust you'll get all of the use you'll need out of this product.
KEY-BAK uses high quality materials to ensure durability. Our SUPER48 Plus Heavy Duty Retractable Keychain's case is actually Polycarbonate, a strong and durable-special plastic.
First appearance seems to be very similar to a regular plastic. Polycarbonate provides excellent impact and weather resistance compared to the average resistance in common plastics. It's been used to make shatter-proof windows, eyeglass lenses and much more- it is a go to for lightweight and durable products.
Feel free to let us know your thoughts after using it after a while. We love getting feedback from our customers!
