The challenge
Conference all-in-one displays are shared by multiple users every day. The stylus pen is the most frequently touched accessory in meeting rooms, classrooms and collaborative spaces, making it a potential carrier of bacteria such as Escherichia coli and Staphylococcus aureus. Regular chemical disinfection is inconsistent and often impractical between back-to-back meetings.
Our solution
The M13 Black Stylus Pen is engineered with an antibacterial treatment on its non-porous plastic surface, designed to inhibit bacterial growth on the pen body during normal use. It is a drop-in accessory for conference all-in-one displays — no change to writing feel, pairing or charging workflow.
Verified performance
Tested by Guangzhou Institute of Microbiology Group Co., Ltd. in accordance with ISO 22196:2011 (Measurement of antibacterial activity on plastics and other non-porous surfaces):

|---|---|---|---|
| Escherichia coli ATCC 8739 | 3.5 × 10⁶ | 0.63 | 99.9% |
