Octopus Write & Draw Ink Blue Koi Waterproof Fountain Pen Ink 50ml

The one ink that I can use for sketching and watercolor wash. It does not smudge at all!

It’s an excellent ink for what it’s worth!! People who enjoy archival nature to either write or draw this may be your ink!!

This is my favorite ink, hands down. I use it in pilot vanishing point medium, hongdian m2 medium, twsbi 580 1.1mm stub. Waterproof, doesn't bleed through paper (usually maruman mnemosyne). You can write your signature with this ink.

Love the color & dry time. It’s a little wet in a TWSBI Eco Fine Nib, but I’ll try it with different pens to see the best fit. It’s very similar to De Atramentis Document Blue, but I’d choose this for the better color saturation.

Absolutely love this stuff. I wanted a drawing ink that I could use in my foundation pens and paint with watercolours after, and this was exactly what I was looking for. It’s a bit on the pricey side compared to the Diamine inks I’m used to, but definitely not as expensive as other inks out there. I have found that you need to make sure that the ink has been properly dried for a few hours otherwise the ink still can have a tendency to run if you try to paint over it too soon. I did read somewhere that it might be best to have dedicated fountain pens for this waterproof ink so I have Lamy pens with different sized nibs that I use with this ink and nothing else, but honestly it rinses out fine with just water that I probably wouldn’t have a problem switching between different inks. Haven’t needed to use an ink flush fluid or anything. I wouldn’t let the ink dry in the pen though just to be safe. Will definitely use again and even try different shades in the range. Highly recommend.

Fijne inkt, goed watervast. Ik ben helemaal om! :)

schetsen en aquarel

Perfect om tekeningen in te kleuren met bv. aquarel

Inchiostro nerissimo e opaco, se lo usate con una stilografica sciacquatela spesso, perfetto per disegnare, forse il miglior nero mai provato.
