Features

• a blindfold seal that can be removed only once.
• For half a postcard.
• It is a blindfold sticker that you can make a postcard from a bank or a card company that you can peel off to see the contents.
• You use it by putting it on information that you don't want to be seen by third parties, such as personal information, customer information, and account numbers.
• The seal is printed in advance, so you can just put the seal on top of the content you want to hide, and the glue uses "black glue" so you can't see through the content you want to hide.
• Once removed, it cannot be reattached, so it is highly secure and prevents third parties from opening.
• About half of a postcard is concealable.
• The surface cannot be printed with an inkjet or laser printer.
• * This product comes with stickers only and no postcards.
• * This seal is for making personal information difficult to see, and does not guarantee that personal information will not be leaked.
• * This seal is prone to warping. If you notice any curl, be sure to remove the curl before use.
