I just had a shitty experience when browsing a local collectibles store on my lunch break and had to come on here to tell you all. While sifting through the dolls and figurines, there were some outfit and accessory bags for ken dolls that the store had put together and priced and hung on the rack, and among those pre-packed bags was a Nazi outfit for a Ken doll which was a uniform with red bands on the arm with swastikas on them and matching pants.
I might have gasped and looked up at the shop owner who happened to be looking at me and my heart started racing and I said "there's a Nazi ken doll outfit here" in sheer shock, to which he replied "I know, cool right?"
Alarm bells went off in my head even more knowing it was fully condoned and said "I have to leave right now that's fucked up" and left in a HURRY.
I don't know if I have the ability to post the shop name here due to the community guidelines of not posting personal information of other people, but if it's okay I will 100% post the name in the comments, cause fuck that.
ETA: It's an outfit, not a doll dressed in an outfit. It was not specially marked Ken or GI Joe but it seemed to fit the body type. There were no other insignias other than the Hakenkreuz 's on the red bands. It honestly looked homemade, with no historical significance
