Made with cotton sheeting fabric. The yarn core makes it soft and lightweight. I think it will reduce stress. ✔️ Slide the knots on both sides to widen it. Put it over the face. Then adjust it to the appropriate size. You can wear it without untying the knots. ✔️ Consider the size of the face and the possibility of the collar getting caught and coming loose. It is safer to choose the size accordingly. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ❁ If you are unsure about choosing the size ❁ Measure the nude size while the pet is sitting. 【= Snug fit without extra space】 The appropriate size is that size plus approximately 3-5cm. The guideline is that you should be able to fit 2-3 human fingers in the gap. For kittens, approximately 2-3cm. It's best if you can fit 1-2 fingers. This is just a guideline, so please use it as a reference. ❁ To keep it clean ❁ Please gently wipe it clean with a pet shampoo towel, etc. ❁ The photo shows the smallest size ʕ•ᴥ•ʔ
