Thank you for viewing! This is a hand-knitted hat made to fit the head size of a ferret! I hope you can use it for commemorative photos, etc. (^^) * Although I make them with care, they are handmade, so they are not as perfect or durable as mass-produced products. Please handle with care. Please purchase only if you understand that they are handmade. ◎ You can adjust it to some extent with the chin strap, even if there are differences in body size! ◎ Materials Yarn → 100% acrylic Adjustment parts → Plastic
