I recently purchased the Clover Small Point Protectors. I was pleasantly surprised by the lime green color (versus the teal that I saw) that I received. They are "gummy" which helps them to stay on. This also makes them a little hard to get off, but insures they won't fall off in the bag.
I like the small and the large point protectors from Clover. I would recommend them and also purchase more in the future.
These protectors stay on your needles. They do fit needles from size 1 to 10. Very handy and I'm glad that I got them. I don't own any size 0 needles so I don't know if they fit size 0.
