The large tray holds your full collection of daily essentials with room to spare.
Full-grain leather. The longer it sits out and gets used, the more character it picks up.
Small and medium are squares. The large is 8 by 5.5 inches folded, and the shape is the reason to pick it: a phone lies along the long side with room beside it for a wallet, a watch and keys. On a desk that's the difference between everything in one tray and everything in two, and it's the size that stops a pile forming next to the tray instead of in it.
It's the same build as the smaller trays, scaled up: one piece of Horween Chromexcel, a solid brass button stud at each corner, snapped into a shallow box and unsnapped to lie flat again. The bigger the panel, the more leather there is to watch change, which is the argument for Natural here. Black and Color 8 are the other two.
