Or sort-of-locking. Push the plunger down and they lock in place, but push the 1/8" nipple down on a hard surface and they'll unlock for re-use. Handy in the shop or craft room for oil, grease, paints, and glues. (Also quite useful for getting liquid medication into the dog.) They measure 3-1/2" long x 9/16" dia and hold 5ml, are graduated in .2ml increments, and have threaded tops. Note the throwaway price.
