Shurhold’s Snap Stick provides long-lasting lubrication that allows sticky hardware to perform like new. Made in the USA, it is non-toxic, biodegradable and it won’t harm fabric or solid surfaces. Appropriate for metal and plastic zippers, snaps, hinges and other small hardware, the solid, wax-like formula applies like lip balm. Snap Stick is easy to apply to only the desired area. The user runs it along both sides of a zipper or on the male snap, then opens and closes the hardware several times. One application lasts for three months.
