Quality in every detail.

PENAC Writing Instruments are made by Kotobuki & Co., Ltd., the world-renowned Japanese manufacturer of high quality writing instruments.

The comprehensive assortment comprises Mechanical Pencils, Ball Point Pens, Multi Function Pens, Gel-ink Ball Point Pens, Liquid inks, PVC-free Erasers as well as Correction Tapes – everything what you need for daily work.

The leads are particularly break-proof, the ink of gel pens is quick-drying and the refills of ballpoint pens convince by their outstanding writing performance. Ergonomic features of the grip zone and surface as well as fashion aspects in terms of colours have been considered in the design of pens.

Kotobuki‘s unbeaten product quality is maintained by in-line inspections at multiple stages of assembly. Every writing instrument is hand-inspected and tested, thus exceeding by far even the Japanese standard. Standardized quality controls guarantee high product quality.

Innovation is always a key issue. It makes no difference whether the product involved is a high quality pen from the classic line, a young, trendy product with a funky finish or a more advanced model.
