Neck circumference: Approximately 25 cm (adjustable) Length: Approximately 11 cm It has a bit of stiffness because interfacing is applied. Adjust the rubber band around the neck and tie it, then tuck the knot inside. Bears, rabbits, etc. are coated with resin. This is handmade, so it's not a perfect finish like a mass-produced item or a professional's work. Made based on a 6 kg Shih Tzu, my family dog. If you have a different size, color, or want a different breed's decoration, please comment. I will make it if I have the materials.
