Product Review

These corrugated cardboard protective picture frame corners are made with professional quality materials (manufactured by ULINE) so they provide real protection. They are the easiest and fastest corners to assemble (they do not need to be punched out of a cardboard sheet that produces excess waste materials). They are adjustable, reusable, 100% recyclable, and 100% Made in the USA. Each corner is designed with an automatic locking tab to help the corner stay on the frame with no tape needed. In the product package, you will find a Quick Start sheet with easy full-color photo instructions. An optional free bonus PDF file is also included that will be sent to you when your order is shipped. The PDF file includes use and adjustment information plus professional storage and moving tips to help you get the most out of your versatile corners. Note: To honor your email preferences, we will not send the optional Bonus PDF If you have opted out of receiving emails from Amazon sellers.
