Hi Yuhong,
We're so sorry about the condition of the hat when it arrived. We understand how frustrating this experience would be and we take all customer feedback seriously.
When a package is damaged in transit, it is out of our control. To make sure you get your items in perfect condition, we will work with the delivery service to take appropriate action. Also, we apologize that our return policy stated that no open packages can be returned due to hygienic reasons.
Nevertheless, we hope you were still able to enjoy the Halloween season despite this mishap and thank you for allowing us a chance to fix this for you. Can you contact us at info@party-expert.com Please let us know if there's ever anything else we can do for you!
Cheers :jack_o_lantern:
