Reddit reviews los ingobernables de Japon cap New Japan pro wrestling Tetsuya Naito

I would definitely check out gaijin collectibles. I just got in the Bullet Club X Tekken shirt and bandana from them Saturday and they were shipped fast at a good price.

Another option may be Amazon JP. They actually carry quite a bit of NJPW stuff.
It looks like they have the L I J hat available to order but it's not expected to ship for 1 to 2 months.
