yep! I also use the Sakuras for coloring in stamps. You don't want to use them on huge areas or it takes a long time, but they give a beautiful sparkle to stamped images!
I used them on the carousel horse on this card. They're opaque, unlike the Spicas which are pretty see-through. Whimsical Carousel By Here Kitty
**The coarse sparkles are loose glitter (mane/tale), but everything is colored with the Sakura Stardust pens.

Oooh, now I really want some Sakura Stardust pens. And if I remember correctly, I think I saw a Scrapbook Memories TV episode one time where they actually used the stardust pens to watercolor with, too. At least, I think it was the stardust pens. I'll have to go see if I can find the episode online to see if that was the pen they used. I like pens and tools you can use for multiple purposes and finishes like that (straight out of the box, or with other mediums).
