Looking to buy the food writer/pen, in black. Preferably the fine tip. Know where I can buy them online?

Global Sugar Art has them......

I had the same question before as I was looking for a good quality black fine tip marker. Hoenydukes had the answer (as she always does!). There were other ideas as well, so here is the post: http://forum.cakecentral.com/cake-decorating-ftopict-595999.html

I ended up getting the Fine Tip Foodoodlers and have been very happy with them.

Yes, it's the Foodoodlers that you want. I've tried the Wilton's and the Americolor and neither brand had a fine enough tip for me. Finally I ordered the Foodoodlers and it was a hit!
