Pentel Ain Stein Leads 0.3mm | Ultra-Fine Mechanical Pencil Refills

Description:
The Pentel Ain Stein Leads 0.3mm are built for precision. Designed with Pentel’s high-density ceramic polymer structure, these leads are exceptionally strong for their size — resisting breakage even at ultra-fine thickness. This makes them perfect for detailed note-taking, architectural sketches, mathematics, technical drawing and fine lined journaling.
The graphite lays down smoothly without scratchiness, producing clear, readable strokes with consistent density. Whether you’re working on engineering layouts, academic notes, diagrams or clean handwriting, Ain Stein provides the control you need without constant lead snapping.
