Great Fit, Hardy, Ease, & Price
I have not needed to use corner protectors until now - wasn’t sure of the quality I would get with these. They were a pleasant and welcome surprise. The flexibility to use on a variety of thicknesses of my picture frames was a great advantage. These are hardy, assemble easily, and do the job intended. Great price for the quantity.

These corners work well
Used these cardboard corners to protect my art work on a cross country move. Once you got the hang of how to assemble them, they worked great. Flexible thicknesses to accommodate various frame widths. Were substantial, not flimsy. I recommend.

Best cardboard frame protector
These were perfect for packing and moving my pictures. It took me a one or two tries to figure out how to put these together, but once I figured it out these went together very quickly. They stayed on various sized frames and actually stayed put, and actually protected the corners. I purchased a second box because I ran out and they arrived very quickly. If I have to move again *shudder* I'll get these again.

Awesome!
These worked great. Once you see how to fold them you can do it quickly. We ordered more and will use them again if we need to move again.

Protection for my frames
I am very happy with the adjustable cardboard corner protectors. Easy to fold and install. The thickness of the cardboard seems fine and I used all 3 sizes. You always need more than you think. Thanks Mr. Pen

Very very good, easy and adjustable. Used on a variety of frame sizings, looked great with added protection. A clean white, substantial protection for framed art for travelling and markets.

These are difficult to keep in shape and too loose fall off or to small they can’t fit. Only 3 sizes. Cheap cardboard. But price not cheap. When you follow the instructions the cardboard is not robust enough to hold the one bed you make and the flap you insert in to create the corner.
