Gorgeous, Fun Ink
I bought this after sampling several of the J. Herbin shimmering inks. I used a J. Herbin glass dip pen to maximize the sheen.
I had some parchment paper lying around and by tearing the edges it makes for a beautiful faux hand-made look. Coupled with this ink, it gives a wonderful look of elegance to your correspondence.
I also tested one of the shimmering inks in a Sailor Fude with good results. I'm away from my desk so I don't have the names but I have two more of this genre on my wish list.
