Thank you for viewing. This is a size M dog collar called the Limited Slip Collar from ComfortFlex, a US company. Key features of the product: * Gentle on the neck: The wide cushion pad reduces stress on the neck and throat when pulling, providing a soft and comfortable feel that dogs won't mind. * Safety: Reflective material is used in the white stripe part of the nylon tape, reflecting light during nighttime walks to enhance safety. * Functionality: It can be machine washed if it gets dirty. Also, the size is adjustable, making it suitable for growing dogs. * How to wear: This type is put on over the head. By adjusting it to fit around the back of the head (the narrowest part of the neck behind the ears), you can prevent the collar from slipping off. This is a new item with the product tag attached. I am selling it because I didn't use it. I would appreciate it if you could understand that it has been stored at home. - Brand: ComfortFlex - Model: Limited Slip Collar - Size: M - Head circumference: Approximately 25cm to 51cm - Width: Approximately 3.5cm - Color: Yellow and black stripes
