Muji Ballpoint Pen Knock Aluminium

The Muji Ballpoint Pen Knock Aluminium is a slim retractable pen with a brushed aluminium body and metal fittings that stay rattle-free. Its 0.5 mm tip writes a fine, low-smudge line, and the gel refill is available in blue, black or red so the body is kept and only the core is swapped. It suits note takers who want a light, inexpensive everyday pen.
