"I ordered these hats for my son's 2nd birthday. When I received the package, I was in shock that the hats were not assembled. They were a hudge pain!!! Each and every one had to be taped because they would not stay in the pre-cut slot's and they would pop back open. Then, after all of this, the strings that holds the hat to the head, had to be tied onto each hole. It took approx. 45 mins to put 16 hats together. Overall, they were really cute and the quality was good. The problem was having to put these things together and the time that it takes. I don't recall that I had read anywhere in the description at the time of ordering, does it say "Assembly Required" . So, lets just say we were not very happy, esp. since I ordered a ton of stuff and most of it had to be assembled. It is a big headache when you have so much stuff to do before a chids party, then you recieve the party decorations and favors and it's not assembled!! SO BE AWARE!!!!"
