I think they just might be the infamous midnight blue and navy suede.
I'm hoping to join the ranks in early March.
I don't know where Frills got his, but I ordered my MTO thru Skoaktiebolaget.
Axels has had them in the past, but do not currently have any in stock. Unipair has also had them, but I don't know whether they currently have them in stock or not.
