Ink Review 

Supplies Used:

Smear Test (Dry Time):

  • 10-20 Seconds – Like Mosthis ink is very 'middle of the road' in regards to dry time, not too wet, not too dry.

Drip Test (Water Resistance):

  • Low – This isn't the ink for important documents, when smeared or dripped on this disappears almost completely!


  • Medium – Between swabs 1-3 you see the biggest difference between 1-2 where when overlapped it deepens from a deep pink to almost a maroon.

Ease of Cleaning:

  • High – We found this ink to be extremely well behaved and was easily


  • Medium-Low – There is a touch of shading with this ink, especially on overlapping lines though you don't see a ton of shading on it own.


  • Medium – Australis Rose goes down smoothly and while not wet enough to bleed through most papers it is certainly not dry.

 Packaging and Aesthetics:

  • Robert Oster Signature Inks use recyclable PET bottles which are manufactured in Australia’s first carbon neutral plastics plant. The opening is wide enough to fill your pen from.

Overall, Australis Rose is an extremely well behaved ink with a touch of shading and is the perfect 'Goldilocks' ink in regards to flow and saturation.
