Lineco, Self-Adhesive Polypropylene Mounting Corners, 1.25 inch Full View, Pressure Sensitive, Non-Yellowing Acrylic Adhesive (Pack of 48)

Lineco self adhesive corners are an excellent method for mounting Postal envelopes in stamp collection albums. The large see through corners allow for protection of edges and easy removal and remounting when inspection of obverse sides is required. Very easy to use!

I bought these for a project I am working on framing some pictures for myself. Overall these were easy to use and work well. My only issue is the corner is visible inside my mat. These are for me personally though so I am not too upset because in the end the product did it’s job. I ultimately just trimmed the corners on the next photo and will do the same on any future projects.

Every single one of the corners split while trying to apply. Worst product for this purpose. Would have returned but didn’t use right away.

These corners work perfectly to keep the vintage posters from sliding down when mounted. I wish they were not glossy though. Matte or satin finish would look better and not take your eye from the art.

Was looking for photo corners to hold thicker vintage sheet music in a frame that regular photo corners wouldn’t. These worked perfectly.

I had problems removing the backing off of the mounts and figured out that you have to go onto the gutter (space between the mounts) to peel them off. It was difficult to see this because both the gutter and the mount have a shiny quality to them. It would've been helpful if this was explained on the packaging. Overall, I am very pleased with the product.

Corners work well for framing when using mats .

Would not peal off the backing. Horrible...would never buy again. Big waste of money
