This set of 12 non opening/locking stitch markers are Adorably Cute! They came nicely packed in a small fabric zipper pouch. They fit up to 19mm needles!!! Smooth & appear they will be snag-free. I feel they look more like mice then cats, but my 11 year old guessed cat when I asked her & her ‘best friend’ is a Mouse named Mousy so what do I know!! They are Super Cute and Handy!
