The pre-engraved Autism medical alert bracelet (no customization) is perfect for those that need a medical ID bracelet fast and at a very reasonable price. Choose from 6 different band designs and 4 colors in the silicone holder. Even glow in the dark! The beauty of the silicone concept is the aluminium medical ID tag will not touch the skin (perfect for those allergic to metals). To make things even better, these bands may be worn every day and in water! Bands are made of nylon with a plastic center push buckle, and adjustable up to a 6.5" wrist. Excess length may be cut and melted with a heat source to keep the webbing from fraying. This ID with silicone holder will also fit any of our nylon medical bands and customized medical ID tags are also available!
