【PomPreece】Wide Donut Elizabethan Collar Gingham Check Pattern - Blue This Elizabethan collar doesn't get in the way when eating, reducing stress during wear. Filled with fluffy, soft padding. Can be used as a pillow for sleeping. Size 1 is perfect for small dogs and cats. Purchased for a cat for 5060 yen and just arrived on 2/20, but I'm selling it because the size didn't fit. I tried it on my completely indoor cat once. Please rest assured that my cat does not have any contagious diseases. It's almost new, only tried on, but since it has been worn once, there might be some overlooked hairs or minor stains. If you want a completely new item, please purchase it from the shop. If you have any questions, feel free to ask in the comments section. Size 1: Neck circumference 18-20cm, Width 9-9.5cm, Thickness 2cm, Weight 100g Color: Blue Material: 100% Polyester (Water-repellent finish)
