The Iris Eye Massager, sounds terrifying right? When I took it out of the box it looked a little bit scary too. There is a quick guide to get you started with a couple of pictures and a teeny tiny printed instruction booklet, the best way to find out how to use the massager is to go to their website and download the PDF for clear instructions. The IRIS comes with a USB charger as well as a microfiber bag, one charge will give you 140 uses so if you use it twice a day (as you are meant too) that gives you just over two months without having to recharge.
