These are bracelet liners, with angled channels. The black insert is a soft velvet, and kind of works for pens, if they are thin to standard size. The white one is leatherette and built the same as the black one, but with a soft vinyl. I like the visibility of the lighter background, but the black is very classy. Each of these has 18 slots. They are also somewhat intrusive in the tray, taking up nearly half the depth.
