Robert Oster Saguaro Green Ink Review & Giveaway: Pen Chalet Exclusive Ink

We got three new Pen Chalet Exclusive Robert Oster inks this last week – and today’s review features a favorite around here: Robert Oster Saguaro Green ink! One of 4 currently available Pen Chalet Exclusive Robert Oster ink colors. See what you think of it based on how it performed during this week’s ink review tests! 

All About the Ink Maker: Robert Oster

Robert Oster is a prolific Australian ink company. We enjoy a great Partnership with Robert Oster himself and currently carry almost 150 of these popular inks. After our previous Robert Oster and Pen Chalet ink collaboration was a smashing success, we decided another joint effort was the best course of action. And now, we’re wildly excited about the three new Exclusive Pen Chalet ink colors. 

All About the Pen Chalet Exclusive Ink Colors from Robert Oster: 

Most Robert Oster inks are a reflection of the landscape and scenery of Australia. We thought it appropriate that our collaborations with the respected Aussie ink maker continue in the same vein. Since Pen Chalet was founded in Arizona, the Robert Oster Pen Chalet collaboration inks reflect the colors of Arizona’s uniquely beautiful landscape. 

Antelope Canyon ink, inspired by the gorgeous slot canyon phenomenon in Northern Arizona, was released in late 2020. Three additional exclusive colors released in January 2021: 

  • Sedona Red
  • Monsoon Sky, and 
  • Saguaro Green

This Week’s Featured Ink: Robert Oster Saguaro Green Ink

All of the Pen Chalet Exclusive Robert Oster ink colors pull from iconic elements of Pen Chalet’s home state, Arizona. This week’s featured ink, Saguaro Green, is a gorgeous shade of green leaning toward olive, which pulls the color of the majestic Saguaro Cactus located in Arizona’s Sonoran Desert. (If you’ve never seen a Saguaro cactus before, look it up! Then visit Arizona to get a picture with one of these striking Arizona icons).

It’s Time: Robert Oster Saguaro Green Ink Review

This week we put Robert Oster Saguaro Green fountain pen ink through our standard ink review tests. And we’ll share all the details right here!

Read the full Robert Oster Saguaro Green ink review.

Ink Review Testing Factors (to keep things scientific):

We used a French-made J. Herbin spiral glass dip pen (with a tip comparable to a medium-fine fountain pen nib) and Rhodia dot pad paper.

Let’s Talk About the Robert Oster Ink Bottle:

Robert Oster Saguaro Green ink comes in Robert Oster’s standard PET environmentally friendly plastic 50 ml bottle with a leak-proof cap. Every Robert Oster ink bottle is identical, with a simple white label showing a representative “sample” of the ink color with the ink color’s name on top of the cap. The gold Robert Oster label wraps around the front of the ink bottle. The Pen Chalet Exclusive ink colors are designated with the added text “ Exclusive” printed underneath the ink color’s name on the cap. Robert Oster inks use no additional packaging (which keeps the costs down). 

How Much Does Robert Oster Fountain Pen Ink Cost?

Robert Oster Saguaro Green fountain pen ink is a reasonably mid-range priced ink for the 50 ml. quantity. Check for the latest discounted price at 

How Did This Week’s Ink Fair in the 1-Dip Test?

We conducted a 1-dip test with Robert Oster Saguaro Green ink using a J. Herbin spiral glass dip pen and Rhodia dot pad paper. (For the 1-Dip Test, we dip the pen in ink once for each of three different writing samples. The three writing samples include: “S,” “X,” and scribble lines. The test looks for how well the ink performs on paper by showing if the pen runs out of ink before completing a full line). Saguaro Green ink very easily wrote across the paper on all three writing samples with lots of ink to spare. 

How Fast Does the Saguaro Green Ink Dry?

Robert Oster’s Saguaro Green fountain pen ink showed a dry time of approximately 6-7 seconds with medium saturation. That’s a reasonable dry time, and we’d recommend it for everyday use. 

Does Robert Oster Saguaro Green Ink Bleed Through?

We saw no bleeding during normal use on Rhodia dot pad paper. We saw some very slight bleeding during the heavy saturated cotton swab test, but only at the most saturated points. 

Was There Any Feathering While Using Saguaro Green Ink?

We saw no feathering during normal use on Rhodia dot pad paper. We did see some slight feathering during the water test, but since this isn’t a waterproof ink, that’s expected. 

How Does the Ink Stand Up to Water?

For the water test, we let an ink sample dry for about 3 minutes before running a wet cotton swab over the sample. Robert Oster ink isn’t waterproof but still performed reasonably well. We saw some light color smearing, but the lines were still legible with some very slight distortion and line fading.

Does the Fountain Pen Ink Have Good Shading Traits?

Robert Oster Saguaro Green ink has very nice shading possibilities with the right nib and penmanship. 

Final Conclusion on this Week’s Featured Robert Oster Ink:

Saguaro Green is a reasonably priced ink for the 50 ml bottle size. The nice, medium-olive green color has some dark shading traits. Made by prolific and well known Australian ink maker Robert Oster, the inks arrive in simple but effective environmentally friendly packaging. The ink also has a reasonable dry time (6-7 seconds). Saguaro Green ink joins Antelope Canyon, Sedona Red, and Monsoon Sky as one of the Pen Chalet Exclusive Robert Oster fountain pen inks inspired by our home state of Arizona. Happy writing from Down Under and Arizona!

I love this shade! My favourite one of the 4. I hadn’t heard of a Saguaro cactus before. It strangely has a soft, velvet look to it, just like the ink. Beautiful!

Don’t let the color of this ink make you think wrongly about saguaro cacti. They are the wine qua non of the Sonoran Desert, our equivalent to Northern California’s Giant Redwood. The first thing to know is don’t touch it, or let your dog sniff one. The spines are some of the sharpest natural plant forms in the world and are barbed as well, making removal of one from skin worse than the initial bite. So it is perfectly suited to become what they all do in old age, two hundred years and up, become bird hotels. They are essential… Read more »

Green is a very beautiful color but the ink result on this Robert Oster is something else. Admire that even the packaging is kept in mind like the leak proof cap and environmentally friendly plastic bottle. Travelers’ ink for sure: Australian but inspired by American landscape. Nice. Would like to have this.
