The IF LOST T-Shirt is recommended for children, elderly adults, mentally or physically disabled, and other loved ones to wear. The front of the T-Shirt displays www.IfLostTags.com and the IF LOST logo across the chest. The Standard IF LOST Tag design is printed on the back. Customers write phone numbers directly onto the T-Shirt on the line under each contact person. For best results, we recommend using a permanent fabric pen to write on the shirt (may purchase separately). For safety reasons, please do not write any names or addresses on the shirt. Please refer to sizing chart for care instructions and sizing.
