Child seat shoulder strap escape prevention! Escape prevention! Slack prevention! Set of 2, white and black (washed) Each has two buckle locks, but the lower lock parts are missing on both, so they cannot be locked. At our house, just attaching the buckles was effective enough, and we didn't use the locks every time, so I think it can be used without any problems! I was stressed because I was worried about my child escaping the belt while driving, so it is highly recommended for children who tend to escape!
