BowenM@kateyj made a post here that is pretty close: https://www.massdrop.com/buy/this-is-ground-penpencil-case/talk/537518
So in the darker brown Cognac case, we have a Pentel Hi-Polymer eraser at top, then from left to right we have a Machine Era brass pen, a silver Rotring 600 0.5 mm, a Blackwing Pearl pencil, then a random no-name brand #2 pencil someone gave me made of cedar, and lastly an Ohto Promecha ballpoint pen.
In the banner, the lighter brown Toffee case from left to right has the ATELEIA Brass Pen, an Aquamarine Italix Freshman's Notator, a silver Ohto Litz gel pen, a Rotring Rapid Pro ballpoint pen, then a blue Pentel Orenz 0.7 mm. Hope this helps!
Here's a shot of both of them filled:
