The slice is elliptical and about as big as your eye. It fits your eye socket well. It feels wonderful, a gel like consistency, cold to the touch (at least in winter) and it moulds nicely into your eye. You are supposed to lie with it on your eyes for 5 minutes. I did this daily for 5 consecutive days and cannot say that I think the dark lines under my eyes look any better.

I did not close the slice properly one day and the ends are a bit hard and dry now, so I am not sure whether that happens over time, or whether it only happened to me because I did not store it properly. After 5 days of use the slice is also markedly smaller than on day 1, about 3 mm around.

It would be a nice touch to a spa experience, to have these cold slices on your eyes while relaxing with a mask. It was definitely cooling and I am sure just the coldness would reduce swelling. (But can't you do that with a cold towel for free?) So it is nice to use, but I am not sure whether there were any actual results. I wish there was.

The slices can be re-used for up to 10 times. It costs about R100 for a pair, thus giving you a cost of R10 per use.
