WHY TOM CREATED IT?
"Too many pens and their refills are disposable by design. Similar to printer ink cartridges, pen companies want you to buy into their format so they can keep selling you replacement pens or refills repeatedly. It's good for their business, but it's bad for the planet and stifles creativity.
As a product designer and craftsman who loves using a variety of pens to create illustrations and designs, I had this very problem! Pens would sit in my drawer for years, either patiently waiting for that very specific refill, or I was just loath to dispose of an otherwise fully functional pen that had run out of ink.
Having designed and handmade calligraphy and fountain pens for creative folks across the world full-time for over 6 years, I decided it was time to apply my knowledge to the pen I used most of all and one of the biggest culprits when it came to its disposable nature: the fineliner."
FAQ
What ink can I use?
The Wren is compatible with all standard Fountain Pen Inks and we have a beautiful range of colours, which are perfect for the Wren. Please note the Wren is not suitable for use with our Shimmer Fountain Pen Inks or Calligraphy Inks.
What are the differences between the Duo and the Single Lumos?
- The Single Lumos has one tip and one ink reservoir, which is double the Duo's reservoir size.
- The Duo Lumos allows you to have two different pens in one body, allowing you to easily change between nibs and ink colours on either side.
How long will the ink/tips last?
You can expect the high-quality, Japanese-made tip to last for months of use. We tested a single ink fill in the Wren on a plotter – a device used for precision drawing – and it wrote consistently for 344 metres. That's the equivalent of 50 A4 pages of handwriting!
When the tip eventually dulls, you can find packs of three replacement tips
Can I purchase replacement tips and reservoirs for my Lumos?
Yes! Everything you need for your Lumos is listed below:
- Full Creative Tip Set
- Tips (packs of 3)
- Spare Ink Reservoirs
- Reservoir & Tip Containers x 3
