This 20 pack of gripper clips are great for securing your plants to plant supports. The package comes with 10 regular 1' and 10 large 1-1/2' clips. They claim to be rust proof but I havent been using them long enough to say either way. I wish I had bought these years ago, as these clips work well on my delicate growths. I expect these to last several seasons, so the price point is very good considering you will get a lot of use out of them. Highly recommended.
