Masque: Raeli is an add-on that adds a skin for Masque.
Note: You must have Masque installed to use this add-on.
It includes one skin, which has a simple 1 pixel black border.
The checked texture has a slight highlight, though this can easily be disabled by setting the checked transparency to 0 in the Masque settings.
Items have a slight internal glow to them that makes it easier at a glance to see item quality.
