The BCW Comic Storage Box is the highest quality, most competitively priced cardboard storage box on the market today. They are constructed of white corrugated paper and have a 200 lb. test strength. Use this box to store and protect all your valuable, collectible comics. These boxes incorporate BCW's latest design improvements so that the box folds together much easier and the corners are clean and square. This was accomplished by changing the corrugated double-wall construction from a combination of B and C flutes to a combination of B and E flutes. Additional benefits of the new design are that bundles of the new Short Comic Box occupy less space, and the E flute on the outer wall provides for a much smoother surface for printing.
