Plug for circular needles to prevent your stitches from falling out of your needles.
Option 3004: SMALL for needles from 2 to 5 mm
Option 3005: LARGE for 5 to 10 mm needles Have a good knitting!
Works as intended. I use them on my circular needles when travelling so that the tips don't poke through my bag. The small ones are handy as I find that most stitch stoppers are for larger needles and end up falling off.
