Materials vary by product listing. Common materials include cardstock (thick card stock), plain paper, fabric (such as felt), and some plastic components; listings will specify the exact material for each hat.
Sellers use several sizing methods: pre-cut holes with elastic bands, adhesive strips, built-in adjustable designs, or simply labeling items as "one size fits most." Product pages often indicate which method is used.
Origin information varies by listing. At least one headband set in the results is labeled "Made in the USA," while many other listings do not clearly state a country of origin.
Listings use a range of age labels, including "Adult," "12 Years and Up," "All Ages," and "3 Years and Up." Check individual listings for recommended age guidance.
