Review on 30Pcs EuTengHao 9X5.5Mm Silver Pin Keepers Locking Pin Backs Clasp Lock by Matthew Guiney

These little things are great! Perfect compliment to my pin collection, making it easy to attach pins to jackets, bags, lanyards, etc. without worrying that they’ll fall off and get lost.Easy to use, and really solid hold! The one thing I will caution is that many pins have a little poker that sticks out to help keep the pins from turning on your clothing - you’ll need to bend those flat down to make this locking pin back have a tight fit against the body of the pin. I don’t have any issues with turning pins once you lock them in tight :-)Will probably be ordering more soon!
