The Ori reservoir is slightly larger and a different length to the Lumos version. It’s also made from a denser fibre, which improves ink flow – especially for thicker, more viscous inks like pigmented highlighter inks. This makes it better suited to broader tips and more demanding ink types.

Precision-crafted anodised aluminium – the same material used in aerospace engineering! Anodising makes the pen durable, with a finish tough enough to stand the test of time and an array of stunning colour options.

Length capped – 142mm
Pen barrel diameter – 12.5mm
Weight – 34g

Of course! The ink dries quickly, so there’s no risk of smudging for left-handed writers.

Yes. Engraving is applied to the dark-coloured side of the pen, such as purple, orange, or blue. If you purchase a two-pen or three-pen set, the same engraving will be applied to each pen in the set.

The Ori is compatible with all of our Fluoro highlighter inks, standard Fountain Pen Inks and Fibre Tip Inks. Please note the Ori is not suitable for use with our Shimmer Fountain Pen Inks or Calligraphy Inks.

We have tested our highlighter with a range of inks and recommend pigment-based inks for the best results and minimal smudging. You can use either of our pigmented inks;

- Fountain Pen Ink No. 60 Pigment Black.

- Platinum Carbon Ink (waterproof pigment ink).

- Sailor Kiwa-guro (waterproof pigment ink).

As with any highlighter, please allow your ink to dry fully before highlighting to avoid smudging.

It depends on the ink.

Our highlighter inks fall into two categories:

Dye-based: Green, Yellow and Purple

Pigment-based: Blue, Pink and Orange.

The dye-based inks (Green, Yellow and Purple) can be used with the Lumos fibre and brush tips. However, they are not compatible with the fineliner or writing tips.

The pigment-based highlighter inks are not suitable for use in the Lumos, as they can clog the reservoir or tips. These are best used with dip pens or calligraphy tools.

Our highlighter inks are designed to be bright, bold and highly visible on the page – which means they behave a little differently to standard fountain pen inks. They’re more heavily loaded with colour, so they flow best through broader tips (like fibre or brush tips) where there’s more surface area for the ink to move through. In very fine tips, this can lead to reduced flow or clogging over time. For the best performance, we recommend using highlighter inks with fibre or brush tips only.

If you’re ever unsure, feel free to reply to this message and we’ll happily point you in the right direction.

It’s simple:

1. Unscrew the tip holder to access the reservoir.
2. Dip the reservoir into your ink of choice and let the capillary action draw up the ink.
3. Reassemble the pen, and you’re ready to write!

We’ve also created a helpful video guide - find it here.

There are two ways to switch ink colours:

1. Rinse the nib and reservoir under warm running water, dry thoroughly, and refill with your new ink.
2. Swap out the tip and reservoir entirely and store the old ones in a ziplock bag or container.

With proper care, a reservoir can last indefinitely if you stick to the same ink.

If you frequently clean and switch inks, you may get around 4-5 washes before capillary action starts to diminish. Don’t worry – we sell replacement reservoirs for when you need them.

Our tips are crafted in Japan and built to outlast many of their competitors. Longevity depends on factors like:

• Paper smoothness (smoother paper reduces wear).
• Tip size (smaller tips experience more pressure and may wear faster).
• Writing style (heavy pressure or techniques like pointillism can shorten lifespan).
• Ink choice (free-flowing inks reduce friction).

Great news though, replacement tips are affordable and environmentally friendly.

You can find our full tip collection and multipacks of your favourites here.

Tips are inserted through the top of the tip holder.

The silicone grip included with your Ori makes changing tips a breeze!
Position the tip grip over the tip itself (not the tip holder) and press firmly to pull out the tip.

Soak them in warm soapy water or our Nib Cleaning Solution for 30 minutes, then rinse thoroughly. There may be a small amount of residual ink, but it will clear out after a few strokes with your new ink.

No, the Lumos tips are smaller and won't fit the Ori's body

Regular cleaning with warm soapy water will keep your Ori in great condition. Be sure to dry all parts thoroughly and check for ink in the threaded sections before reassembling. A touch of silicone grease on the threads will help maintain a smooth seal.

Store your spare reservoirs and tips in our handy containers (or a ziplock bag) to prevent them from drying out, keeping them ready for future use.

If a reservoir or tip is inked, it must never be left to dry out. Always store inked parts in an airtight container. If ink dries inside, the reservoir or tip will clog and can’t be used again.

We recommend storing your Ori horizontally in a cool, dry place to keep it in tip-top condition.

This can happen if a reservoir or tip is left uncapped or allowed to dry after inking. Dried ink can clog the reservoir or tip and make it unusable.

To prevent this, always store inked parts in an airtight container.

Don't worry - we sell replacement reservoirs here. Replacement tips can be found here.

The reservoir may not be fully loaded. Try dipping it in ink again for 10–20 seconds and ensure it’s securely reinserted into the pen.
