Special Kawaii Onomatopeia edition of the Pentel Energel. Combines two commonly used things in Japanese language:

• Onomatopeia, where a word sounds like what it represents.
• Doubling-up a word to either emphasise it or apply a more specific, or entirely different, meaning. 'Doki' is the sound of a heartbeat in Japanese, but it's far more often used as 'doki-doki', an excited or rushing heartbeat, just like you might have at the thought of these super-cute pens. Or you might have a Doki-Doki Morning playing Doki Doki Literature Club. Just Monika.

In this edition, the pens represent:

• Fuwa-fuwa - fluffy, especially used for these delicious-looking pancakes.
• Puru-puru - soft or squishy. Like this soft, squishy pudding.
• Hoka-hoka - sizzling or steaming, like hot food. Fried treats surround what appears to be a monkey enjoying fresh food in an onsen.
• Kira-kira - sparkling, often used for the stars in the night sky.
• Saku-saku - light and crispy, when used for food, as here. Can also mean things are going smoothly or running well.
• Suya-suya - sleeping peacefully, like these sweet cats.

The Pentel EnerGel Xm Retractable rollerball is the latest EnerGel pen, boasting a stylish metal-look barrel. There's a rubber grip area with grooved fingerprint pattern, and a metal pocket clip. Pentel claim that their hybrid liquid gel ink is smoother flowing and quicker drying than ordinary gel ink.

Refillable with LR7 refill.
