My zBoard has minor residue/blemishes, is this normal?

This is normal and is caused by friction from packaging materials we use to keep your product safe during shipping. To get your zBoards zesty clean, just wipe off with a slightly damp cloth and voila, problem solved! If it still doesn't come off or looks like a damage, please contact us with your information and pictures of the issue so we can be able to further assist you.
