Using these LP mailers is easy. First, decide whether you need to fold the box to 1/2' or 1'. Then, place your record albums gently inside the mailer. If you want extra protection, add some bubble wrap around the albums before putting them in. When shipping, make sure to seal the mailer properly. As for maintenance, keep these mailers in a dry place to prevent the corrugated material from getting wet and losing its strength. If they get dirty, you can gently wipe them with a dry cloth.
