Today’s inks are from the Robert Oster Elements collection. You can finds these inks for sale at a lot of retailers, including Vanness Pens.

Swabs:

Left to right: Earth, Fire, Water and Wind.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry Time: 20-40 seconds

Water Resistance: Low

Feathering: None

Show through: Medium

Bleeding: None

Other properties: Earth and Water have medium shading, Fire has low shading, and Wind has high shading. Water has blue shimmer.

On Walmart Pen + Gear copy paper there was some feathering and bleeding in the larger nib sizes.

Earth is lighter than Birmingham Antique Sepia.

Fire is similar to a lot of other inks.

Water is closest to Nemosine Blue Snowball Nebula Twinkle.

Wind is close to Sailor Ink Studio 243.

I used a Taroko Enigma notebook. All four had slightly dry flows.

Overall, these are lovely inks. I do wish the flow was a bit wetter, but they are lovely to use in wetter nibs.
