Moonlit Voyage | The Paper Mouse x Opus 88 Mini Fountain Pen

A small restock of the Moonlit Voyage pen is expected mid to late January, followed by a larger restock in spring 2026. Please keep an eye on our newsletter and social media for restock announcements!

Take a magical trip through a dreamy night seascape with our Paper Mouse and Bear friends. We partnered with OPUS 88 to design a fanciful mini pen inspired by the illustration from our Fly Me to the Moon Logical Prime notebooks. Follow the Mouseon its trusty paper airplane through the moonlit sky around the pens cap. Below on the pen barrel, the Bear ventures on the ocean waves in an origami boat.

This mini pen is made of smooth resin with metal accents, and the screw-on cap can be posted to extend the pen’s length. The pen barrel is a transparent blue color to match the night scene and offers a large ink capacity, thanks to the eyedropper filling system. The shutoff valve inside helps prevent leaking. Unscrew the blind cap at the end of the pen when you’re writing to allow ink to flow, and tighten it up when you’re traveling to shut off the ink supply.
