This is a harness belt to prevent children from escaping from their child seats. I bought two, but this one is unopened and has been stored in the closet without being used. I believe it's an older model of what's currently sold. I used it in my car's child seat for about 3 years without any problems. It's well-made and my child was able to sit without escaping. - Product Name: Harness Belt - Brand: SUCFORTS - Purpose: Child safety belt - Target Age: For infants and toddlers Thank you for looking.
