Here is testament to Kincaid markers. We were taking out some trees and a few trimmed up. Well as it would happen a tree fell in the middle of my newest bed. That's just the way the tree wanted to fall. All the markers were walked on or pulled up. All the markers but one survived, some were bent and could be repaired, the labels were intact. The one that didn't make it, the label was curled and couldn't be removed from the stake.
So glad I made the decision to use Kincaid markers. Of course my husband and neighbors apologized profusely.
