Purchased from the Cuckoo Couture official website in October 2025. Originally intended as a belly warmer and neck warmer. I planned to use it to protect the permanent tracheostomy of a 1.6kg Chihuahua. However, the size didn't fit, so I'm selling them. One has been tried on the neck and washed. Two are new. This is a pet belly warmer made with fabric processed with terahertz ore. It stretches very well. The size chart is attached in photos 2 and 3. Please refer to them. One cost 4400 yen including tax. The terahertz effect is said to remain unchanged even after washing. Can be used as a snood, neck warmer, etc., in addition to a belly warmer. Recommended for dogs with hernias, weak stomachs, and senior dogs!
