Sanford 13401 permanent marker fine bullet tip black

Sharpie T.E.C. marker for technical use

The Sharpie T.E.C. permanent marker uses a fine bullet tip to lay down consistent black lines. Each unit carries a batch-identified ink supply for traceability in documentation workflows. It suits engineers, lab staff and quality teams who need permanent marks on paper, labels or hard surfaces. The 13401 model is sold new and ready for immediate use.

Sustained writing without tip deformation

The fine bullet tip holds its shape during long marking sessions, avoiding the flare that broadens lines on lesser markers. Ink flow remains steady so repeated strokes keep uniform width and density. Batch-coded ink ensures every marker in a batch behaves the same way across shifts. The design supports continuous use in documentation-heavy environments.
