Robert Oster Avocado Ink

Robert Oster Avocado Ink Review & Giveaway!

Robert Oster Avocado Ink is a 2018 addition to Robert Oster’s ever increasing ink lineup from Down under.  Pushing 100 ink varieties, the Robert Oster signature ink series uses names and colors that envelop the entirety of Australia’s geography and way of life.  We proudly carries a full complement of all Signature inks as well as the recently added Robert Oster Shake ‘N’ Shimmy line.

Robert Oster Avocado ink is quite an interesting color. The ink is a muted soft green color, like the color of the inside of an avocado, but also has a darker green shade with a hint of soft pink sheen.  It seems that Robert Oster Avocado ink might actual change color when fully dried vs. when it was applied.  Being a medium saturation ink the color is beautiful and shows up dark enough on paper to make it legible.  Although relatively new in the industry, Robert Oster inks are consistently a pleasure to work with and produce some of the finest ink colors on the market today.

Continuing reading for a chance to win the bottle of Robert Oster Avocado Ink we used for this review.

Robert Oster Avocado Ink Review

Robert Oster Avocado Ink Review

We found the following traits during our review of Robert Oster Avocado ink that we hope you may find useful when choosing your next ink purchase.

Testing Factors

For our review of Robert Oster Avocado ink we used French made Rhodia dot pad paper with a J. Herbin glass dip pen.  The glass dip pen has a tip that is similar to a fine fountain pen nib.

Bottle Size

Robert Oster signature inks come in very basic yet functional environmentally safe 50 ml. plastic bottles.  There is no outer packaging with Robert Oster inks, with each bottle containing an ink color label and color swatch on the top of the lid.


Robert Oster Avocado ink retails for $17.00 in the USA.  Other Robert Oster inks, such as the Shake ‘N’ Shimmy series retail for a bit more.  This makes Robert Oster Signature inks a mid ranged priced ink option and extremely reasonable considering each bottle is imported directly from Australia.

Dry Time

We found a dry time of approximately 7-8 seconds during our review of Robert Oster Avocado ink.  This dry time is very acceptable and allows for Robert Oster Avocado ink to be used in most situations, at home or the office.

Bleed Through

During our review of Robert Oster Avocado ink we found absolutely no bleeding using Rhodia dot pad paper.  Even during the water and cotton swab tests we found no bleed through during our review.


During regular use we found no feathering on Rhodia paper.  Even during our water test we found no significant line distortion and feathering.

Water Test

During our water test, where we run a wet cotton swab over a dried sample of Robert Oster Avocado ink, we found some very slight color distortion and a small amount of line distortion. Overall, Robert Oster Avocado ink held up very well under this test for a non-waterproof ink.

Shading and Sheening

Robert Oster inks are known for their wonderful shading traits.  Robert Oster Avocado ink is no different and even may excel in its shading characteristics.  We found lots of color variations from a nice soft muted green to a darker green with numbers of shades in between.  Mixed into these different shades of green comes a slight pink sheen as well.

Conclusions about Robert Oster Avocado Ink

Robert Oster Avocado ink is a unique soft green color that has lots of nice shading possibilities.  This would be a wonderful ink to use in letter, journal or note writing.  The medium saturation allows for this lighter green ink to still show up well on paper.  It has a reasonable dry time, will flow well and is a good value for imported ink with a nice large 50 ml. bottle. Happy Writing from Australia!

Growing up in the sixties and seventies Avocado was a very popular color. This ink is a nice looking Avocado.

I love Robert Oster inks! My only problem is that there are too many for me to try!

This looks like a great subdued green and the shading and sheening is nice. I’d love to try it!

Green is one of my favorite colors. It isn’t the most work appropriate color, and that’s exactly why I love to use it! Hee hee!

My favorite ink is Caran d’Ache Storm. I’d love to see a review of inks that are close to that color.

Hard to tell onscreen but looks very similar to Bungubox Tsuyuhikari – a comparison would be great!

I haven’t tried any Oster ink yet. This looks like a lovely subdued green. The shade would be good to render ricefields. I have a couple green inks… a Parker Quink green and a PB ‘pogi’ Ink made by Diamine which looks similar to this shade.

This is another great ink from the creative genius of Robert Oster. As always, I would love for you to review some old standby inks from Waterman and Sheaffer.

Avocado sure looks a lot better as an ink than it did as our old refrigerator! If you haven’t yet, I’d love to see a review of Krishna Jungle Volcano.

Been falling in love with green inks, I’ve been on a Alt Goldgrun kick lately. I wonder how this compares?

I was on the fence about this ink – I really wanted to try it but a lot of greens have been hit or miss for me. I decided to get a sample first, but I ended up liking it a lot; I should have just gone for the bottle!

I really like the shading of this ink.

It is interesting how ‘mossy’ and soft the ink appears to be. I haven’t seen many green inks that have such a finely defined earthly texture while still being light. The minor shades of pink are a lovely accent to the color as well.

Would you consider reviewing an ink with similar characteristics, but perhaps in salmon/cherry blossom pink, or some sort of purple/blue?
