Disney has so many things under 100 dollars! Turtle Buckle up buttercup you just flipped my witch switch shirt I would say buy them their favorite Disney movie on a DVD or Blu Ray. My cousin is a big fan of Disney like me but he loves Marvel and Disney’s other live action films more. So I bought him a Blu Ray edition of Infinity War and limited time Disney store exclusive Infinity War Mickey Ears. He absolutely loved it! Whenever he goes to Disneyland he always wears that! He watched Infinity War dozens of times! This is the some of the best you could get. I would also say a mug or shirt. I bought my other cousin a Finding Dory mug and an Ariel shirt! She also loved her gifts!
You’re at an age where many are desperate not to be Turtle Buckle up buttercup you just flipped my witch switch shirt deemed ‘childish’ and so they deny themselves the fun of for example watching Disney movies and enjoying the Characters. Who knows how many of them would love to visit Disney land/World and meet the princesses or similar .. even if they’d loudly deny it if you told them so. (I would expect them to happily watch said movies with their kids if they have them.. as that way at least they have an ‘excuse’.. which is quite ridiculous). So.. Feel free to watch whatever you want and don’t listen to those that want you to deny yourself something fun because someone else say its only for certain age groups. Which.. Have fun essentially.
