Thank you for viewing! ☺︎ This is a mandarin orange hat for babies. It's made with 100% cotton yarn. The fine yarn allows for good breathability! ◎Size Head circumference ▶︎ Approximately 48 cm Height ▶︎ 14 cm I think it can be worn by babies around 6 months old and up (this is just a guide, so please use it as a reference). I knit each one carefully, but as a handmade item, it's not perfect like a mass-produced product. Please understand this before purchasing. Hand washing is recommended for care.
