I lose bookmarks right and left, so I have switched to the magnetic page markers. These work awesome! The magnets extend the entire length of the clip on both sides. Other clips I've tried only have a small magnet on each side which results in the marker design getting damaged over time because the design extends 1/8" - 1/4" past the magnet. I have been using these for several months and they are in perfect condition, just like new.
