It's day 2 of KWZ week, so let's take a look at KWZ Gummiberry. Thanks to Pen Chalet for sending a sample over for review.
Gummiberry is a medium, saturated purple.
When pooled, this ink turns a dark purple, almost black.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 15 seconds
Water resistance: Low
Feathering: Low-there was quite a bit of feathering in the flex nib on Rhodia, but other than that there was no feathering.
Show through: Medium
Bleeding: Low-there was some bleeding on Rhodia and Tomoe River paper, but only in the flex nib.
Other properties: No shading, no sheen, and no shimmer. There is some small variation in color, but not enough that I would call it shading. It does look different in a fine nib than it looks in a broad nib, but that's not shading.
On 20 pound copy paper the ink behaved well, no issues that I noticed.
I used a broad Twilight Vanishing Point on Tomoe River paper. The ink had a lovely wet flow.
Overall, I like the flow of this ink, and it has a lovely purple color. Give it a try, you might love it.
