UNI Posca Acrylic Marker Medium Tip Refill Nib x 3

The UNI Posca PCR-5 refill nib set is designed to extend the working life of PC-5M medium tip acrylic markers by restoring their original flow and line consistency. Each pack includes three replacement bullet nibs that can be installed quickly, allowing worn or clogged tips to be replaced without discarding the entire marker. This makes it a practical solution for maintaining performance in busy studios, classrooms, and makerspaces where markers see frequent use.

Each nib delivers the same 1.8–2.5 mm medium line width as the original, supporting controlled application for illustration, lettering, and surface work across paper, wood, metal, glass, and plastic. The reversible design allows the nib to be flipped for extended use, helping to maximise lifespan while reducing material waste. Compatible exclusively with UNI Posca PC-5M markers, this refill set keeps your tools in reliable working condition with minimal downtime.
