L size plaid Elizabethan collar, made of polyester and lightweight. - Size: L - Design: Plaid (red, blue, green) - Material: 100% polyester Thank you for looking. This item is in good condition, having only been used a few times by my dog. It's made of fabric, so it's light, and my dog didn't seem to be very stressed by it. The size is L. For reference, my dog is a Shiba Inu, around 8kg, and it fit just right.
