Cap-N-Lock has introduced its new combination locking cap, designed to work with existing prescription medication bottles.

The cap was designed to help families prevent unauthorised and undetected use of prescription medications for non-medical purposes.

It combines a four-digit combination locking mechanism with a sturdy PVC construction, and is easy to use, the company claims.

The locking cap also features a compact design that allows easy access and storage when travelling and at home.
