Hmmm, strange!
Took a screenshot so you know what to search for.

10 slots that's divided into 5 per side, with a divider/cover between the two sides so the pens aren't colliding with each other. If you take a look at the review photos, looks like the retainer loops are small and elastic enough to accommodate thin to thick pen diameters.
There was this one as well but it didn't look as nice and I prefer the longer single retainer loops vs the two small ones. (Not sure if this link won't work either!)
