Mr. Pen- Adjustable Cardboard Corner Protectors, Fits 1", 1.5", 2.1" Frames, 100 Pack, Bulk Edge Protectors for Shipping, Paintings, Picture Frame, Packing Item Edge Protection

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 were easy to use and worked great to protect my art while I was moving

These were a little tricky at first to make sure they were assembled corrected since you have to fold them yourself. The price was right but you can tell they are on the cheaper side in terms of quality. Once assembled they are easy to slip over the corners - we build custom furniture and after placing on the corners we then wrapped additional plastic over them to keep them in place since they definitely wouldn't stay in place on their own. They serve the purpose well and we would actually buy these again.

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

These little corners are great! Easy assembly and they’re really sturdy. I love that they come flat so storage is a snap. Great purchase!

Perfect product for moving or storing framed art. Fits snugly around various framing widths. After adding a layer of bubble wrap to protect the whole item, each corner gets a corner protector to hold it in place. The protected art can be carefully stacked for efficient transport. Easy instructions. These durable corners can be 'undone' and saved for a later move and shipment. Very useful!

Not very sturdy. Yes they fold up nicely and have ability to size according to how thick the frame is but I had to double them up bc cardboard just isn’t sturdy enough to really do the job they are intended to do

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.

I can't fault these. They are so handy and easy to put together and a further plus is that they are adjustable according to your frame size. I've just bought another pack to avoid damage to framed pictures in transit.

These are so good, sturdy and easy to assemble, perfect for posting frames! Very reasonable price for such good quality. Will deffo be ordering more!

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.
