Please take note: This product is custom-made and cannot be returned or exchanged for reasons other than quality issues. Due to the handmade nature, there may be small imperfections on individual helmets, but as long as they do not affect the overall appearance, they are not considered quality problems and cannot be returned or exchanged. Heads up: These props are handmade and may have marks, so perfectionists should steer clear. Suitable for head sizes up to 60cm (Please double check your head circumference before purchasing as non-customized sizes cannot be disputed). Made from fiberglass with a flip-up visor, this one-size-fits-most helmet features light-up eyes. Don't forget to open the back of the helmet before putting it on!
