Wow! and um not so wow.
UPDATE 6/24/19: I've found with all the colors of Clair, that heavy application causes the ink to bleed while it's drying. Bummer. Bleed not just through paper, but also sideways. Normal stamping does not have this problem.

MY ORIGINAL POST: I went for this new VersaFine line of stamps because it's VersaFine. I've used the original Onyx Black VersaFine since it came out. Wonderful detail -- holds the finest shading and lines on rubber stamps. The Clair line... I tried to find out what the difference was, checked for reviews, and Tsukineko web site... no luck. So I picked a few colors, Fallen Leaves was one of them. Honestly, I was underwhelmed. Clair doesn't hold details as well, but it is opaque without being globby and wet, which are characteristics of pigment ink pads. This Fallen Leaves color isn't the deep, red-brown printing on the ink pad cover either; it's just black. So, what's the WOW?! I just used a fingertip dauber, this ink pad, and a stencil... WOW! Better than any stamp pad out there. I am utterly blown away. I was able to get opaque black with very little effort as well as semi-transparent. I wish Fallen Leaves were the grungy brown I can only dream about, but you've got to buy Clair if you want to do small stencils. Because of the pigment ink stencils do not rinse off, but I grabbed a Lysol wipe, and it came right off.
