PrevaGuardTM products contain an EPA registered antimicrobial additive that is molded directly into the pen's plastic components and should last the lifetime of the pen unless the plastic is destroyed. This helps protect the pen by suppressing the growth of bacteria, molds, mildew and fungi, especially in high-moisture environments.
