As long as you keep the chocolate Lollipops wrapped they will stay fresh for around 2 to 4 months.
Just be sure to keep them wrapped and away from anything that may cause them to absorb odors from other foods.
After 4 months the chocolate lollipops won't be fresh but they will still be safe to eat after that time.
Aside from wrapping them up it's best to store the chocolate lollipops in an airtight container to keep them fresh.
