Better Than A Solid Ring Marker
Locking stitch markers have a clasp that makes them removable. You can also place these markers anywhere, not just on your needle. For example, you could slide the marker through the middle of a stitch, which is handy for dropped stitches, short rows and more. (You can always sub in a locking marker for a ring, but you should never swap a ring for a locking one.) If you crochet, you’re team locking stitch marker all the way.
