Using these cake slice boxes is a breeze. First, take the flat box out of the package. Fold along the pre - marked lines to assemble it into a box shape. You can place your favorite treats like cupcakes, cookies, or candies inside. For personalization, you can add a ribbon around the box, or stick some cute stickers on it. As for maintenance, keep them in a dry place to prevent the paper from getting wet. Since they are made of paper, avoid exposing them to water or high humidity. If there are any small marks, you can gently wipe them with a dry cloth. Have fun using these boxes for your special events!
