These are small leash swivel snaps that help you keep your pooch from spinning around in circles after a few too many trips around the fire hydrant.  Nickel plated steel, these are our light duty swivel snaps, for small leashes or narrow belts, in the 1/4 inch neighborhood.  Sold one at a time (or ‘piece by the each’ as we say in Maine) for $5, a pack of 10 for $8, or $70 for a bag of 100, and all include free USA shipping.  Yup.
