I've tried a lot of lawn edging variants over the years. This one is the easiest to install & humbly does it's job.

Exactly what I was looking for and should fit the bill nicely for my front walk. It’s been installed for three months now and so far so good I was looking for something that would hold Mulch back in the landscape bed so that it wouldn’t wash into my front walkway and this looks like it could be it.

Flexible Steel lawn Edging
Nice design and should stand up to some harsh NYS weather. We will be ordering more now that we've seen the product and tested it first hand.

Excellent Product
We just installed 3 packages of the 4” corten steel Core Edge product. Very easy to do. Erin was most helpful via chat to ensure we had the correct dimensions to encircle our new fire pit. We would highly recommend this edging for just about any application in one’s lawn and gardens.
