Yeeks! I can't believe they're raising their faceup charge to $66 it's way off the rest of the pack... hope this isn't a trend.

Let's see, the difference between a custom faceup and a default is that with the custom you get to choose what you want it to look like. For example, with luts you could send them a series of photos or a written description of the makeup you wanted and they would attempt to fullfill your request... the default makeup on the other hand is the exact faceup that you see in the photos (with a certain degree of variation since they are handpainted) .
If you choose not to get a faceup you will get a blank doll, without any makeup at all... for an example of what this looks like try looking up Yder's head in their parts sections.
Hope this helps.
