^Yep, Caviar 31 is the name of the line. The Flap comes in three sizes, the Hobo comes in two sizes, and there is also a large Tote version as well. The SA describes it as a soft iridescent caviar and they are available in grey, black and brown.
Small flap dimensions ($2175): 6" x 6" (tiny)
Medium flap dimensions ($2450): 20 cm x 36 cm x 10 cm
Large flap dimensions: still pending
Small hobo dimensions ($2525): 26 cm x 39 cm x 16 cm
Large hobo dimensions: 30 cm x 45 cm x 16.5 cm
Large tote ($3100): 31 cm x 42 cm x 16.5 cm
The Chanel boutiques supposedly only ordered the medium flap and the small hobo. The Las Vegas Bellagio store (Carrie was the SA I spoke to) has one black flap, no hobos but there are a couple of black hobos scattered across the US according to the computer. It's new so they are expecting more in. NM will soon get in the small and medium flaps (black and brown), the small hobo (gray), and the large tote (black and brown).
That's the info I have on it so far, C!! Will let you know if I hear more!!
Regarding the other size flaps/hobos...you need to contact the department stores for availability! HTH
