Create amiibo cards yourself?

I see more and more people on the internet selling amiibo cards that don't come directly from Nintendo. For example, the micro-amiibo cards are not original Nintendo goods. Is the sale prohibited? Then I would point it out to a seller on Ebay.

Yes, the sale is prohibited as it is not an official Nintendo product.

As for your tip… No offense, but you don't need to point out to sellers that it's illegal, they usually know that.

And there are enough people who really enjoy using these cards.
