This is a very cute handmade付け襟 (tsuke-eri, detachable collar) perfect for everyday wear! I knitted it softly with knitting needles (*´˘`*) It's made with soft yarn, 60% acrylic and 30% lamb's wool, but please be careful with newborns and those with sensitive skin. For care, you can hand wash it in lukewarm water! When drying, please lay it flat to prevent stretching (*ˊᵕˋ*) Neck circumference: approximately 32 cm, width: approximately 7.5 cm It can be adjusted with the ties, so it can be used for a long time! I have photographed the colors to be as close to the real thing as possible, but please understand that there may be some variation due to lighting conditions, etc. m(*_ _)m
