Create a personalized shirt, hoodie, coat, onesie, or backpack decal on any smooth surface. The decal is made of durable, water-resistant vinyl. It does NOT work on rubber, ribbon, plastic, or rough surfaces. Feel free to contact us if you need more clarification. When placing your order for a decal, please provide the following personalization information: color, font, design/text, and width. (See the chart for a list of available fonts.) Note that the size is based on the overall width of the area it'll be applied to. Height is measured from the tallest point to the lowest point. Length is measured by the most extended word/phrase or shape. If no font is selected, the Captain Comic default font will be applied. A message will be sent with the proof for your approval. Once your approval is received, the order will be processed. Your order will be shipped with detailed instructions for care and application of the decal.
