How to use: Put on the hooded jumpsuit first, making sure it fits well. Then put on the mask to complete the biohazard look. Note: This suit is for fancy - dress use only, not for real biohazard protection. Avoid sharp objects that may tear the suit. Maintenance: After use, simply hand - wash the suit in cold water with mild detergent. Hang it to dry. Don't use a dryer as it may damage the material.
