I could talk about this all day- I am such a box nerd. I never tire of thinking and talking about this leather.
I returned for holiday and am comparing my box Kellys from various years. The ones from 1977 and from 1992 are creamy, buttery, a bit more lightweight, and baby soft. Beautiful patinas but that could also be attributed to age and meticulous care.
My 2002 black Sellier is thick, almost tough, with a very smooth mirror-like patina. It was my first Kelly and had been my workhorse bag for years. It has been through the ringer. My puppy chewed three corners and it was sent to Paris for 9 months to fix. It was redyed (black, the original color) by the marvelous Docride because it had color loss. It has a few water blisters but still is beautiful with the shiniest patina of all.
The other two Kellys, 2003 and 2008, both have a sheen to the box leather, almost a bit of shimmer/sparkle in the right light. They are very smooth but not at all soft or buttery, and neither has much of a patina yet.
Comparison pics to come!
