Adding to Cart Added to Cart

Platinum Carbon Ink is renowned for its deep, archival black and exceptional permanence.

Crafted in Japan using ultra-fine pigment particles, it delivers a rich, dense black that holds its ground confidently under watercolour washes. It’s a favourite among artists and illustrators for good reason.

Performance & care – a quick heads up
Because this is a pigment-based ink, it behaves a little differently from our dye-based fountain pen inks.

It’s compatible with all of our pens – The Lumos, Wren, Field Mouse and our Fountain Pens. If you’re using the finest fineliner tips in the Lumos (0.4 and below), here are a few helpful pointers:
  • If you won’t be using your pen for more than a few days, remove the tip and reservoir, rinse thoroughly with water, and allow everything to dry completely before refilling.
  • Avoid storing your Lumos vertically (tip up). Ink can flow away from the nib, leaving it less saturated and more prone to drying out – even when capped.
  • If pigment ink dries inside a tip or reservoir, it can’t be revived due to the pigment particles. Simply replace the tip and reservoir and you’re back in business.
A little care goes a long way. In return, you’ll get crisp, permanent, archival black lines.

*Waterproof? Almost. This ink is highly water-resistant once fully dry. It will hold beautifully under a light to moderate colour wash. Very heavy, very wet overwashes may cause slight movement, so we always recommend testing before committing final marks to the page.
  • Each bottle holds 60ml of ink.
  • Sailor Kiwa-guro is acid-free, non-toxic and vegan.

A Near Perfect Drawing Ink

This carbon ink is popular with artists for a reason, it lays down a lovely line, flows well and is waterproof to washes when it dries. Its the perfect companion to the Wren I purchased and allows for professional results when working outdoors.

Meh

I used The Wren (which I love) with a brand new fine tip nib and brand new ink cartridge on medium grade office paper and Tomoe River paper when trying out the Platinum Carbon ink. The result was not thrilling. The writing appeared broader than the results I get with a Tom’s ink using the standard nib. It makes me think there is some bleeding. It takes several seconds to dry so smearing for this Lefty is an issue. After an hour left to dry, a wet finger smudges the ink.

A series of waterproof inks would be wonderful especially sepia tone for sketchbook artists. Than...

I love it

Platinum carbon ink versus # 60 waterproof Ink

I really like the #60 black ink but found that it was sticking or drying too much in the smaller nibs. I prefer using a .2 nib for most of the work that I do. I'm still using the #60 ink in the larger nibs but for the smaller nib the platinum carbon ink works amazingly well.

Glad you have it in sortiment

In my opinion best ink for Lumos pens. Once dry it is permanent with almost any other media. I use it since years in my artwork.

Great Ink to use with watercolor

This ink does not bleed when used with watercolor. It makes my Wren adaptable to my writing and drawing needs, at will!

When a company asks for a review a product that never came...

This is a very poor joke. You are asking me to review a product that I ordered on the 1st of May and still haven’t gotten (it is the 20th of May). It was sent to the wrong country - Germany instead of Poland, and then after finally arriving in the right country has been held up by customs with no help on your side (you claim to take care of customs). I am currently fighting with them to release the package. I ordered the WREN and this ink for my brother, so that he could write his finals with it (they were on the 13th, so now it is way too late). The shipping from Tom’s studio is a complete joke. Such an unreliable company. I am truly sad, cause I had great hopes. I just hope that the gift arrives at some point in the future… And seriously, asking me for a review of a product I have been waiting for the last 20 days is just mean. Do better.

Hi Alicja,

Thank you for taking the time to leave your feedback! I’m truly sorry for the disappointment and frustration this experience has caused you.

Our review requests are automatically sent 14 days after dispatch, so I completely understand how upsetting it must have felt to receive that prompt before your parcel even arrived. I’ve just had a look into your order and can see it’s been delivered today. I’m so sorry it didn’t arrive in time for your brother’s exams and we can imagine how special that gift was meant to be, and we’re gutted it didn’t get there when it mattered most.

While we do estimate 3–5 working days for international delivery from the dispatch date (28th April in this case), customs delays can unfortunately extend this timeframe, and we always aim to be as helpful as we can in resolving those issues.

Please do let me know if you still haven't got your parcel and we can investigate immediately. Here to help if you have any further questions.

Warm wishes,
Rachel

Tom's Studio

Great!

Once dry it doesn't budge. You get a huge amount for the price so this will last me a long time!
