Thank you for viewing my work from among many others! This is a detachable collar. I crocheted it with cotton yarn that is easy to use in all seasons. It's the type that ties with strings, so you can adjust the length around the neck. The yarn has glitter in it, so it sparkles slightly when it catches the light ✨ (I apologize that it's difficult to convey in the photos) I was particular about the mermaid-like color scheme! It can be worn by children, as well as pets such as dogs and cats ☺︎ Even dogs who don't like clothes will find it easy to put on! My dog was able to wear it smoothly when I put it on at the same time as the harness or collar during walks ☺︎ It's also recommended for walks, outings, and taking photos at home ☺︎ The model dog is a 2.2kg Toy Poodle. Neck circumference: Approximately 26cm Tying string: Approximately 19cm on one side Collar: Approximately 5.5cm Yarn: 95% cotton 5% polyester 【Color】 Base: 【Glitter】Pink x Blue ✼ I make each item with care, but because it is a handmade product, there may be some misalignment or distortion.
