Ultimate Eco Period Starter Pack (with Eco Period Cup, Underwear & Pads) This pack allows you to get started on your zero waste period journey. If you use a cup and / or wash out your panties daily, it could see you through your whole cycle, because you also have pads for use whilst your underwear is in the wash and you can wear your Eco Cup menstrual cup day and night, for up to 12 hours between changes. Underwear and pads can be worn alone with no backup, or as a backup to your Eco Cup menstrual cup. Having a range of sustainable, reusable sanitary product options gives you the option of trying out what works best for you, before you invest more in a particular product.
