The Deco is rich with color. Here it is in Ruby, Ivory, and Amethyst. I believe it also came in Ebony, but I haven't come across one in that color. They're made from Italian calf leather and are lined inside with cream suede. They are stunning to me.
The clasp reminds me of the lock-and-key diaries I had as a young girl, so I inserted some lovely journaling cards and keep them on my side table.
