The NO-BUGS pen is made of a special antibacterial material. This material has been enriched with silver ions, which reduce the settling and growth of bacteria on that surface by up to 99% throughout the life of the pen. In the era of an epidemic, when our awareness of how easily infections are transmitted through everyday objects is growing, it will be a gadget that shows how much we care about safety and hygiene. Retractable white pen with blue refill.
