All our pins come with 2 rubber clasp pinbacks, creating a tight fit to secure the pin. Rubber clasps are light in weight, skin-friendly, easy to remove, and held down by friction. Upgrading to a deluxe locking clasp would provide a more secure placement of the pin and keeps the pin in place. A deluxe locking clasp is a safer option if the placement of the pin experiences lots of movement (eg. backpack, scarf, lanyard, keychain).
