You can make this product more personal by adding a little something of your own choice. Making them personal means adding your name or initials and number. You just need to write in the box below, the name and number of your choice (e.g: Ronaldo 7 or Messi 10). Customised products are created just for you. That means we cannot accept returns, except for manufacturing defects. Customization is not available on items that are pre-printed with a name or number. If you select customization on an item that cannot be customized, we will send the item without customization.
