It is not recommended to reseal a blind bag once it has been opened, as this can compromise the integrity of the packaging and potentially damage the toy inside. The purpose of blind bags is to provide a surprise element, and once the package is opened, the surprise is revealed. However, if you do need to reseal a blind bag for any reason, you can use a small piece of clear tape or a sticker to seal the package back up. Just be sure not to damage the packaging or the toy inside when opening or resealing the blind bag.
