Miscellaneous CALISTA OVULATION TEST KIT

Calista is a no-fuss test that enables you to tell quickly and easily when your most fertile days are. All you need to do is take a sample of saliva from your tongue and place it on the optical block of your tester, let it dry for five minutes and then focus the image through the lens. The resulting pattern indicates whether you are in a fertile period or not.
