I've found what is very likely the last possible source for the G-Star Blade Slim jeans made with Spark Denim and the proper 3D Aged wash.
In Denmark.
http://www.deres.dk/shop/g-star-jeans-blade-2527p.html While I never got a reply to my hastily-translated e-mail asking about shipping to the U.S., I'm inclined to think they can't as the account creation form only lists Denmark and Sweden as possible countries.
And so, I'd like to ask if anyone here is either from Sweden or Denmark, or knows anyone from Sweden or Denmark who would be willing to talk to me about purchasing them and shipping them for me.
If anyone is, please message me.
