It can be hard to tell what is official Naruto merchandise and what isn't. I've found that the larger chain retailers tend to carry party supplies that are officially licensed. That said, I thought they were limited in style. With the popularity of Naruto, I honestly thought there would be more variation in the official Naruto party supplies. ETSY is an excellent option if you are okay with purchasing from small businesses that might not have official merchandise. You can usually find much more variety for Naruto Party Supplies.
