The Tom’s Studio Lumos is now available in a brass special edition, in all three sizes.

I love fineliners and fibre-tipped pens, but unfortunately I have a terrible time making one last for it’s entire life cycle. Either the tip wears out on a disposable pen before the ink runs dry, or in the case of a cartridge pen, the (expensive) proprietary refill cartridge dries up and requires replacement before I get any decent amount of use out of it.

Enter the Tom’s Studio “Lumos” refillable multi-tipped pen, which was designed to solve just this problem. The Lumos has a cotton reservoir that refills by capillary action, meaning that all you have to do is dip the end into an ink bottle to fill. The same mechanism feeds the fibre tip and keeps the ink flowing as you write (or draw, or highlight, etc.). The Lumos Pro ships with eleven different writing tips so that you can use the pen as any combination of fineliner, brush pen, or chisel-tip marker.

The Lumos Pro Duo accommodates two different tips at once, allowing you to alternate between sizes. The cap and barrel feature o-rings to keep the tips from drying out, and the cap can be posted on the back while writing. (The second tip is stored inside the barrel, and you unscrew and invert to write, as shown in the photos.)

The standard Lumos Pro features a single tip, but also incorporates a larger reservoir to allow you to write for longer on a single fill. Both Lumos pens measure approximately 6 inches long and weighs approximately 3.5oz / 100g.

Tom’s Studio describes the Lumos as “infinitely refillable,” meaning that both the tips and the capillary filler are intended to be rinsable and reusable (assuming you use fountain pen ink or another ink that can be easily cleaned). While both tip and filler will eventually wear out, they are inexpensive to replace. (Replacements sold separately.) The Lumos ships with detailed instructions on how to fill and refill the pen, as well as replace the various components. Tom’s Studio has a detailed How-To Guide on their website.

The box includes the pen, 11 different tips, and a small bottle of black ink to get you writing immediately.
