REAL tag on the real version of the same pair of ears. You will notice that things look very similar, but the real tag has an FAC number and is made of a less shiny fabric. These are two things that you can go by, however, keep in mind that there are always exceptions.

Distinguishing authentic Disney Parks Mickey ears from high-quality counterfeits requires a close inspection of tags and materials. Real ears sold in the parks or via the Disney Store will always have a branded fabric tag sewn into the inside of the headband, which usually features the "Disney Parks" logo and a specific SKU or barcode. Authentic ears use high-quality, sturdy fabrics and have tight, consistent stitching; fakes often have visible glue residue, loose threads, or flimsy ears that "wobble" when you move. One of the best indicators is the headband itself: official Disney headbands are designed to be "one size fits most" and have a soft, velour-like lining to prevent slipping, whereas fakes are often made of cheaper, harder plastic. Additionally, look for the holographic sticker on the paper hang-tag, which is a standard security feature for official merchandise. If you are buying a "Designer Collection" or limited edition pair, they will often come with a certificate of authenticity and specialized packaging. If the price seems too good to be true—such as $10 for a pair that normally retails for $35 in the parks—it is almost certainly a counterfeit or a non-licensed "boutique" version.
