Gem 39

Welcome to Hidden Gems — a new corner on our website created for true collectors who love rare, unreleased, and one-of-a-kind creations.

Here you’ll discover pens that never made it to an official release — early trials, artist drafts, spontaneous ideas, and magical little accidents we simply couldn’t let fade away.

Some gems exist as a single piece, others in just a tiny handful — but none of them will ever be restocked. Once a gem is claimed, it disappears into a private collection forever. We’ll add new Hidden Gems from time to time, whenever inspiration strikes and our experiments bring something too special to hide.

There are no names, no stories, no rules here. Just pure imagination. You’re free to give each pen its own name, its own purpose, its own soul. So dive in, explore, and see what calls your name. Your next hidden gem — your true collector’s secret — might be waiting right here for you!

This pen glows beautifully in a dark and semi-dark with a light blue color after an hour exposure to light. Please accept variations in duration of glowing depending on exposure time to light, and the intensity of the light source. There are different light sources you can use for "charging" the pen to glow—natural sunlight, regular desk lamps, or LED lamps. Usually, LED lights produce a weaker glow compared to sunlight and traditional incandescent bulbs. However, avoid overheating especially when using incandescent lights and direct sunlight during "charging". Long exposure to warm sources with strong overheating (over 50°C / 122°F) can degrade the quality of the resin.

Please bear in mind that the photo may slightly differ from the actual item in terms of color due to the lighting during photo shooting or the monitor’s display. 

This fountain pen comes with a standard international converter and one long blue ink cartridge. You can also convert it to eyedropper fill.
