How to use: First, help your toddler put on the padded jumpsuit. Make sure the attached boot tops fit well over their feet. Then, put the fabric headpiece on their head and adjust it for comfort. Finally, strap on the soft fabric eye mask using the Velcro strap. Your child is now ready to transform into Hulk! Attention: Check the size before buying to ensure a proper fit. Be careful with the fabric eye mask, as the Velcro can catch on other things. Maintenance: You can gently hand - wash the costume in cold water with mild detergent. Hang it up to dry. Avoid machine - washing and using harsh chemicals to keep the costume looking great.
