Look at the link at the bottom of my post. I have been using these for a year now, and will continue to use them forever. I use them on tubes, worms, beavers and any other soft plastic. I started using them on beavers because I was having a problem finding a good hook to use. Some hooks were too small, others were too big. From time to time, the beaver would not sit straight and it would slide down the hook. I found these and will not look to another style of hooks.
