The Pentel EnerGel is a renowned line of gel ink pens, specifically the BLN155 model shown here which is part of the liquid gel ink family. The brand Pentel originated in Japan, founded in 1946 by Yukio Horie as The Japan Stationery Co., Ltd. Pentel is credited with inventing several revolutionary writing tools, including the felt-tip pen and various mechanical pencil technologies.

The EnerGel series is celebrated for combining the best qualities of liquid ink and gel ink for a smooth, fast-drying writing experience. These products are primarily manufactured in Japan, where the company maintains its core production facilities.
