Using these swim goggles is super easy. First, adjust the head strap to fit your child's head comfortably. Make sure the goggles sit snugly around the eyes to prevent water from getting in. When your child is done swimming, rinse the goggles with clean water to remove any chlorine or salt. Then, let them air - dry. Avoid leaving them in direct sunlight for too long as it may damage the goggles. Remember, these are assorted items, so the style you receive might be different. If you have a specific style in mind, leave a note in your order. And if you want to be sure of the style, it's best to visit your local Toyworld store.
