30 x 5 x 24 Inches Picture and Mirror Shipping Boxes - 20 Pack Heavy Duty Moving Boxes for Artwork, Frames & Glass - Secure Packaging for Home Moving & Storage | BS300524FOL

Used these to move long distance across the country. Had to move art, mirrors, framed photos and other delicate items. They held up very well, i added extra bubble wrap inside around the corners for more protection, and made sure a layer of bubble wrap was between the box and the item. Nothing was broken, even though it was moved by the movers and we had no control over handling the items. I'd buy them again if we needed to make another long distance haul.
