I've got nearly all of them..pens and brushes.....haven't used them as much as I thought I would on my cards...have "shimmied" up a couple of stamped images...but what I have used them for is after I've painted my air dry clay molds I've used the winks on top of the coloured parts. It's very subtle, and doesn't make the impact that I would like....it's more of a gentle shimmer...much like the Sakurus really, just have to catch the light. JMO...HTH x
