Disney Pixar Alien Design Knit Hat 48-50cm - Color: Bright yellow and blue - Size: 48-50cm - Design: Alien character - Material: 100% acrylic Thank you for viewing. Size: Approximately 24cm (height of hat portion 17cm) x 17cm (width) I bought this to go to Disney and used it for only one day at the park. My child only wore it for a short time, so there are no stains, tears, or frays, and it's still in good condition. I hope someone else can use it.
