In this video I do a full, no-shortcuts swatch marathon of the entire Diamine Inkvent 2025 set—all 25 inks—specifically to show how wildly different they can look depending on paper. I swatch every day’s ink and call out what it’s doing in real life: shimmer that actually shows up (or doesn’t), sheeners that go nuclear, and the more subtle shaders that can get overlooked if you only see one photo online. If you missed the calendar or you’re trying to figure out which bottles are worth buying, this is the “full reveal” version with practical notes instead of hype. The big comparison is Tomoe River vs. Clairefontaine. I test flow, shimmer behavior, and writing performance on both, then circle back for detailed side-by-side swatch comparisons and writing samples. If you care about sheen, Tomoe River is the paper that makes a lot of these inks shine, but Clairefontaine can give you a cleaner, more controlled look depending on the ink. By the end, you’ll know which inks are the massive sheeners, which ones are more everyday-friendly, and how paper choice can completely change the vibe of the same bottle.
