Nintendo’s latest keychains contain real controller parts that can be used 

Nintendo’s second line of “Controller Button Collection” capsule toys has an unlisted feature buyers might not know about. Unlike the first line which had purely cosmetic keychains featuring buttons from the NES and Famicom controllers, this second line (pictured above) includes working analog sticks and buttons from the Super Nintendo, Super Famicom, N64, and GameCube. 

This discovery was made by Nintendo enthusiasts who were quick to rush out and get some of the keychains so that they could try putting the buttons and analog sticks in their respective controllers. Here’s one user’s account: 

A few people who were able to get their hands on these keychains have taken them apart and put the pieces into their associated controllers. Reports show all the replacement parts working, including those for the discontinued GameCube controller. Nintendo likely provided the molds for the controller parts to Bandai (the keychains’ manufacturer) so that it could replicate them for the official keychains. 

Unfortunately, these keychains can only be purchased from Nintendo stores in Kyoto, Osaka, and Tokyo. Those passing by Japan can also get them at Tokyo’s Narita airport. Due to the random nature of gashapon capsule toys and demand for the working parts inside the keychains, there is a high chance that people will snag as many of these as possible to get the ones they want. Still, putting working controller parts inside keychains is a great way to showcase the storied history of Nintendo consoles.
