- Quality materials: The safety seat clips are made of high quality zinc alloy and plastic, delivering durability and resistance to damage while remaining soft and comfortable for use around your child. - Suitable size and compatibility: The clips measure about 23 cm (9 inches) in length and about 9 cm (3.54 inches) in width. They are suitable for baby 5-point harness systems and for safety seats whose buckle can be removed. If the buckle cannot be removed, this product cannot be used. - Enhanced safety and stability: The crotch buckle helps locate and guide the seat strap to ensure the child’s safety. It strictly controls the opening force of each buckle to prevent accidental unlocking by the child. The harness includes a high-quality buckle that is easy for adults to operate but difficult for babies, helping to maintain safety and stability during use, including mealtime. - Easy installation and removal: The belt features a metal lock clip to hold the safety seat base firmly in place. Install the Japanese buckle on the bottom of the seat, adjust the shoulder strap, and thread it through the five-point harness. Once installed, unlock by pressing the red button.
