Here is a Clear Plan Easy Fertility monitor in its original box with instruction booklet.  This monitor typically identifies up to 6 days of fertility, stores your personal fertility information, counts your days & tells you when to test and displays your level of fertility every day.  Requires 4 AAA batteries included.  Test strips not included but can be purchased seperately online or at your local drug store.  Comes from a clean house and device has been well maintained.  High bidder to pay shipping.  I accept money order or paypal.
