Mr. Pen- Adjustable Cardboard Corner Protectors, Fits 1", 1.5" and 2.1" Frames, 40 Pack, Corner Protectors for Shipping, Cardboard Packing Corner, Packaging Edge Protector, Cardboard Shipping Corners

An essential item for moving. Protects anything with corners. Television, art work and picture frames to name a few. Easy to assemble and adjustable. Great value.

Worked well and fit on the corners of my hardcover book to protect it during shipping.

I've used a lot of corners, some of which were bulky but good, and others which were flimsy and needed tape on each one to barely do the job they were designed for. These corner protectors are simply the best: not bulky but easy to fold and snap together crisply and firmly. Highly recommend.

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.

We have moved a bunch of times - so I save these and bought more too. We have some large artwork and some small artwork - all of which are treasures to us. Being able to make the size for each of those corner guards is great for each frame as several are thick and some thin. Then cover art with tissue paper and wrap in large newsprint paper which Amazon has or even their 48" bubble wrap. Then slide into the shipping box. Did same with televisions. After 18 times moving, I am glad I found what really works. And buy the more expensive tape - the cheap is junk and peels right off the boxes.

No instructions, so you have to figure it out yourself. Once you make them the smaller size it is almost impossible to make them wider. They keep collapsing. They do a fair job. You will probably have to tape them on for them to stay put. Now, I was a custom framer and I used cardboard corners all the time. These are not at all like the ones I used in my store. Those had something on the inside that made them stay put on the corner of the frame. These do not. That is why you need tape to hold them on the frame. They are also expensive for what you are getting. It will cost you $1.00 per frame to use, since you need four corners. So, 40 corners do 10 frames. Just be aware.

Fantastic and inexpensive. These worked great for a move. Loved having the different frame sizes they could fit on. I did use painter’s tape to hold them on.

Easy to put together- works perfect!
