Original and licensed accessories, which are generally tested by Nintendo, can be identified by two things that appear on the packaging and/or instructions:

1. The wording "Licensed by (the Trademark of) Nintendo ...". This wording is of course absent in the case of our own products.
2. The golden "Original Nintendo Quality Seal". This consists of a circle with gold indentations and a white surface on which the above wording is inscribed in gold letters. The Nintendo name is shown as our logo. In the lower right corner there is a small "TM".

The quality seal guarantees that you have bought Nintendo quality products.
