Opus 88 Mini Fountain Pen in Matcha Kawaii

Settle into your favorite cozy spot with a fresh cuppa and a matching pen in hand. It’s time to take a refreshing, tea-time dip into our latest pocket fountain pen collaboration.

Step into your favorite neighborhood café every time you uncap the Opus 88 Mini Matcha Kawaii fountain pen. Charming boba tea cups, frothy matcha drinks with cute little smiling faces, and delicate pink cherry blossoms (sakura) swirl together across a vibrant lime-green cap and translucent acrylic barrel.

Steep your deskscape in cozy cafe vibes. Fill up the Matcha pen with your choice of bottled fountain pen ink using the included eyedropper. The translucent barrel holds approximately 1.5ml of "writing juice," while Opus 88's signature shut-off valve prevents any unexpected leaks or burping when you are sipping and journaling on the go.

Serve up your daily notes with total "kawaii" comfort using this handy, high-capacity, pocket-friendly fountain pen!
