Soooo I got roped into making a Kindle cake, (dark grey version) and I was wondering if they sell white food pens or how i would achieve the pearly white effect for the details on the cake itself thanks for the help!!

I don't know about white pens but you can get white food coloring or white airbrush coloring and paint with it. The food coloring needs to be thinned with vodka but the air brush colors you should be able to paint directly with.

Also if you use white fondant you can dust it with pearl dust to give it a sheen. Fun cake
