Hi, I think the shape is better and it has more structure. The selleria one sinks into a slouch I’m not as keen on when worn unlocked. I would have opted for the lambskin in black if it came with silver hardware. Also I just adore lambskin, so tactile, soft and luxurious.@BlueCherry, I have a Nappa mini peekaboo I adore and was thinking of adding a selleria version in a different color—just curious why you prefer the lambskin?
