DRILLOG is a brand of writing instruments that focuses on metal dip pens with a unique structure based on the themes of "exploration" and "dialogue".

The brand name "DRILLOG" is a word coined by combining the words "DRILL", which is also a cutting tool and means repetition and drive, and "DIALOG", which means conversation. Like a drill going into the ground, we want to explore the universal appeal and potential of writing instruments and create products that generate a rich dialogue.

We unveil the iconic DRILLOG symbol: the drill nib. This distinctive emblem stands for precision, creativity and a resolute commitment to a flawless writing experience.

Manufactured using meticulous CNC metal cutting, the nib achieves impeccable precision in the creation of writing lines.

The 0.5 mm width is a versatile choice, ideal for delicate letters and sketches, while the 0.8 mm width works perfectly with glitter and viscous inks, adding an enchanting dimension to your creations.

For ink aficionados looking for generous flow, the 1.2 mm character width is an attractive option. This line width lets you take advantage of the richness of the ink, supported by an innovative ink retention structure that guarantees uninterrupted writing.

Engraved spiral grooves on the body of the pen act as ink reservoirs, enhancing the efficiency of your writing sessions by accommodating a substantial ink reserve.

It's important to note, however, that the drying of the ink can influence the writing area, depending on your pace.

Welcome to the world of DRILLOG - a celebration of thoughtful design, versatility and the harmonious union of form and function. Discover the drill nib - a signature innovation designed for discerning writers and creatives.
