Lumos Pro Duo - Refillable Multi-Tip Pen - Lilac

That's a fantastic question and a core part of what makes the Lumos Pro Duo eco-friendly! You can use most fountain pen inks with it, and we recommend our own range of pigment inks as they are beautifully suited for smooth, long-lasting writing and drawing. However, it's best to steer clear of calligraphy inks because they contain acrylic binders that can clog the pen's fine feed. Also, really experimental inks with heavy shimmers or iridescence might not perform as well, so stick to more standard formulations for the best experience.

Great question for artists! The Lumos Pro Duo is designed to be your go-to creative tool. It comes with a comprehensive set of 11 professional artist tips right in the box. This includes a variety of fineliners (0.1mm to 1.0mm), felt-tip options (chisel and bullet), and a flexible brush tip. You'll also get two writing tips (0.3mm and 0.5mm). It's truly a multi-tip pen system ready for sketching, drawing, lettering, and everyday writing right out of the package!

Absolutely! The Lumos Pro Duo is ingeniously designed for convenience and creativity. You can easily unscrew and swap out the tips on either end of the pen. This means you can have, for instance, a fine 0.1mm fineliner on one side for precise details and a flexible brush tip on the other for lettering or adding washes of color. You can even fill separate ink reservoirs with different ink colors and switch those out too. It's like having a whole pen set in one elegantly refillable body, perfect for artists and eco-conscious writers alike.
