Surfstix makes plugs with them, saw his pictures of them and they looked great. Here are a few I have recently done. I like them. Priced $6.00 to $8.00 a kit I think, (without hooks). Great for guys without a lathe or sander.
Using Rip Plugger's plug making instructions on them I have been happy with them so far.
