Detectable refills can extend the life of your detectable pens / highlighters. Take a look at our patented, fully metal & X-ray detectable retractable pen refill!
Our detectable refill change process applies to our standard, gel, fine-tip and cryo ink refills for our HD & Elephant detectable pen range.
Using another pen or pointed object, push the catch button at the top of the pen to release the end cap & refill housing. After removing the internal refill housing, replace the refill and re-insert the refill housing into the pen, ensuring the catch button is aligned correctly.
