Gray knit hat, approximately 22cm in size, featuring a soft material. - Color: Gray - Size: Approximately 22cm - Material: Cotton knit Thank you for viewing. This is a simple gray knit hat. I apologize, but there is no tag and the material is unknown. However, it's not wool, and I think it's probably cotton. My child didn't complain about any itchiness. Although I'm not a professional inspector, I didn't find any stains, fading, or holes. I hope to sell this to someone who understands that it is a used item. Thank you very much. Instant purchase is OK.
