If you are mailing framed artwork or frames of any kind, then you know protecting the corners is a must! These corners will protect your frame and avoid damage during shipping. Available in sets of 20 or 25 corners.
Cardboard corners have a bright white finish and are scored so all of the folds are smooth and clean without the messy dotted line perforations.
The corner dimensions are 3-1/2" x 3-1/2" and are adjustable. They have two folds to fit frames from 1/2" to 1-3/8" deep so they're much more versatile than single-fold corners.
Made of 200# test corrugated cardboard. They arrive flat, but are very easy to assemble (takes about 5 seconds)! They have a locking tab which folds under and locks the corner on most frames so you don't need to staple or tape them in place.
