A brand overview for the V-mail series of inks can be found here. Noodler's V-Mail Operation Overlord Orange is another good orange developed by Nathan Tardiff. The ink's shading is good, and it is better lubricated than most oranges.
Where To Buy (No Affiliate Links)
Shading: On ink resistant papers this ink is quite a good shader but all the fun is sucked out of it when you move to absorbent stock. Remember, life's too short to use cheap paper.
Bleed Through: Bleeding is pretty aggressive on Copy paper and Field Notes.
Show Through: The back side of Rhodia is great, Field Notes and Copy paper are a write off.
Saturation: Above average saturation.
Water Resistance: This ink is partially water resistant but this property is not very present when used on ink resistant papers.
Drying Time: Longer than average, 30 seconds using an EF nib on Rhodia.
Flow: This ink flows well with good lubrication. I usually find oranges to be dry so this is a nice change from the norm.
Cleaning: Easy to clean out of a pen. A few flushes with a bulb syringe and you are done.
Colour Make Up
Bright yellow leads the ink trace followed by a light pink. The pink component can be seen to be permanent as is evidenced where the sample was placed on the wicking media.
This is a nice orange, it doesn't shade as wildly as Apache Sunset but it isn't as dry either. Habanero is still my favourite but this one is good too and it dries better. The thing with oranges is that you have to use a very wet nib on ink resistant paper to get the phenomenal shading, finer lines on copy paper just look pedestrian.
Whenever orange inks are reviewed the question comes up, can the ink under review replace the now discontinued Sailor Jentle Apricot. Well, I don't think that this can replace Apricot but it is closer than any other ink that I have tried. Apricot is a brighter orange (which doesn't translate very well in the scan below) and it doesn't shade nearly as nicely as the Noodler's ink. Given the choice I would add Operation Overlord Orange to my collection before Apricot. Heresy, I know.
