Is there such a thing?

Don't know, but I'd love one - it'd be great for adding eye-highlights on figurines.

Just wanted to re-ask this question. Does anyone know of a WHITE foodmarker out there?

I haven't found one yet...

NO because the white-white is a powder suspended in the liquid. For eyes you can use the white-white straight from the bottle on a fine brush.

have you used the chocolate writers? I LOVE them. come in all colors. Can get them at local cake/candy supply store.

Chocolate writers? I've never heard of these. I have to look them up.

You can make one.  Here's a tutorial: http://www.lilaloa.com/2012/11/make-your-own-white-food-color-marker.html

There are empty food color DIY pens.  You pull them apart, dip the wick into the color needed (over night) and put the pen back together the next day and use.  I have a set.

Denise, what brand are the markers you have?
