Thank you for viewing! My dog has a habit of biting at their skin, so I made this for protection. It also helps to protect their ears when they scratch them with their paws. :::::::::::Size::::::::::::::::: Neck circumference: 20cm Width: 9.5cm Sponge sheet No cotton Velcro (2.7cm) Seersucker fabric (thin) Weight: 20.1g :::::::::Orders::::::::::::::: I am accepting orders. If you are interested, please comment with: Your dog's neck circumference The width of the collar Sponge sheet only or Sponge sheet and cotton Snap button or Velcro *If you make the Velcro on the neck circumference longer, the Velcro on the outside will also be longer, so I usually attach it around 2-4cm. ::::::::::::::::Fabric Selection::::::::::::::: If you tell me the number of the color you have seen in my previous listings, I will check the stock. Many of the fabrics are out of stock. *I am not familiar with fabric materials, so I describe them as thick, normal, or thin. ::::::::::::::::Cotton Availability::::::::::::::::::: If there is cotton, the collar will be puffy, which will fit closely to the face, but it will also be heavier. If there is no cotton, it will feel loose, so you can narrow the opening angle of the collar, but if you narrow it, and the width is long, it may make it difficult to drink water, which could interfere with daily life. :::::::::::Requests:::::::::::: Please refrain from purchasing if you are looking for perfection like a ready-made product, as this is a handmade item. Thank you for your understanding. ::::::::::::::::::::::::::::::::::: Elizabethan collar Prevents licking wounds Prevents scratching ears Pet supplies Dog supplies Dog clothes Cat fashion collar
