Currently theyre only available in grey. I already placed my preorder. I went with this one instead of AA since it's cheaper. I hope I like it! I just tried preordering it with the 30% off code on LB and it worked (code: 2011). I just checked for exclusions on their FB and they didnt mention the Treesje exclusives being excluded. So it's worth a shot.
They also have a exclusive Sedgwick too. For a few dollars less than Magnolia/Metro:

No pictures as of now. The Sedgwick is slated for an end of January release, hopefully they'll have pics up by then.
