I loved the design and was very happy with it, but I'm selling it because my child has outgrown it. It's a size S-M, suitable for children aged 3-6. It's been used for several years, so there are scratches, stains, fading, and scuffs. The helmet itself is well-made, so I think it can still be used. Please check the condition in the photos and purchase with the understanding that it is a used item that has been used by a child. --- Quoted from the official website --- Kids' Girls' Helmet (Recommended age 2-6 years) The recommended age is a guideline. We recommend measuring your child's head circumference and checking the size chart to see if it fits the recommended head circumference. The NINA model is designed for girls, with safety, comfort, and cuteness as key features. It features a pop color scheme and design that girls love. Equipped with bern's unique technology, ZIP MOLD +, it achieves high impact resistance and a lightweight, comfortable feel. The visor-equipped inner part of the head, which tends to sweat, can be removed and washed, keeping the helmet itself clean. The EZ-FIT inner system, which allows for easy size adjustment with Velcro, is also used on the back of the head. You can easily adjust the fit to match the size of your child's growing head. It supports everything from bicycle rides for pick-up and drop-off to active scenes like balance bikes. S-M Recommended head circumference 51.5-54.5 Kids' helmet, bicycle
