Cardboard Corners

Cardboard Corners

Twikart offers many different varieties and sizes of carboard corners. Most corners have a flap which allows the corner to lock in place to ensure the protection of your items.  Our corners fold and have a locking tab which goes over the front lip so you don't need to staple or tape them on the frames in most cases. These are quality American-made products manufactured exclusively for us. Ours are the industry standard in cardboard corners.

 Made in America

THREE SPECIFIC REASONS TO BUY CARDBOARD CORNERS FROM US:

  • Our corners are scored not perforated - this means that all the folds are smooth and clean 
    without the "dotted line" perforations.
  • Most of our cardboard corners are adjustable - this means they can be folded in two or 
    three different widths so they're much more versatile than single-fold corners which will 
    cost you the same or more from other vendors.
  • We offer quantity discounts for multi-box orders and you can mix and match corners on 
    larger orders for the best combined pricing. We will automatically give you the multi-box 
    price on larger orders, or you can call for a specific quote before ordering.
