If you're in Japan and likewise me you need to 3d print something you'll encounter some trouble because the japanese printing service are quite complicated to use even if you speak japanese. The most annoying part is that some of them need you to subscribe and surrender your data before getting a quote for the printing service. This guy at treatstock is very professional (there was a little adhesion problem with my item and he reprinted it without me asking him to do so) and very quick, the item being in my hands 3 days after the order. There is also plenty of communication during the manufacturing process. I'm completely satisfied and I strongly recommend his services.
