## Customer feedback

Customer feedback highlights smooth writing, comfortable handling, ink flow and perceived reliability, with some customers also considering the pack good value. Experiences with ink life are mixed, including reports of pens running out after two to three pages and others saying the ink lasts a long time. That uncertainty matters for bulk or frequent writing, where consistency and replacement frequency may be important. The listing's 1.0 mm point claim should also be weighed against a separate 0.7 mm line-width entry.
