Requires certain public schools to advertise availability of free menstrual hygiene products.

This bill requires New Jersey public schools that already provide free menstrual hygiene products (tampons and sanitary napkins) to prominently display information about their availability throughout school buildings. Specifically, schools must place notices in locations like nurse's offices, bathrooms, and locker rooms. The law defines "menstrual hygiene products" as tampons and sanitary napkins used during menstrual cycles. It takes effect immediately, ensuring students can easily find these essential items.
