Introducing Tom's Studio - Lumos Mini, the answer to disposable pens. With the versatility and refillability of its big brother, this pocket-sized pen eliminates the need for 100 billion biros in landfills. Say goodbye to wastefulness and hello to big ideas with the Lumos Mini!

The Lumos is designed to work with dye-based inks, which flow beautifully through the reservoir and nibs. These inks generally don’t have pigment particles and binders that can clog the pen.

Which inks work?

Fountain Pen Inks (all of which are dye-based) that don’t contain particles (such as shimmer inks) or binders (like acrylic or shellac).

How many times can I fill the reservoir?

If you consistently use the same ink and take proper care of it, the reservoir can last indefinitely.

However, if you frequently change inks and wash out the reservoir each time, the capillary action might be affected, limiting its lifespan to about 4-5 washes. We offer reservoir containers that make it easy to switch between different ink colours while maintaining their condition. Once a reservoir is fully used, we do sell spares.

How can I change the colour of the ink?

There are two ways:

Flush out the nib and ink reservoir under a warm running tap. Dry all parts thoroughly and refill with another ink. There may be a small amount of the previous colour but it will quickly blend out.
Replace the tip and reservoir as needed. Just take out the previous tip and reservoir and store them in a zip lock bag.

How do I clean the tips?

You can soak them in either in warm soapy water for about 30 mins and flush through with water afterwards. You may have a little bit of ink left over in the tip, but once you refill with a different ink it will write out after a few doodles!
