Dear Miho, Thank you for your order. ◉ Size: Approximately 50 cm (with request) Dog knit hat. Each item is carefully finished by hand, so there may be slight variations in the finished product due to the knitting method, knitting tension, and yarn used. This is a stretchy knit hat. * We will compress it slightly for shipping. The dog has stuffing inside, so please shape it after arrival. Material: 100% acrylic I knit with all my heart, but it is handmade. Please purchase only if you understand. Feel free to comment. ‎(^^) #knithat #handmade #newyearcard #babyhat #crochet #knitting #kids #babyknitting #kidsknitting #crochet
