Quick Fix for Tired Eyes
Size: 1 Count (Pack of 6)
These feel great and really help reduce puffiness and dark circles under my eyes. Super refreshing and easy to use, especially in the morning or in the evening before going out.

Difficult to stay on
Size: 1 Count (Pack of 6)
Won't stay on your face. Only a few patches come in the box for a few days. Price sounds good until you realize the quantity isn't much. I did not notice any difference.

Great product you should try
Size: 1 Count (Pack of 6)
I love these patches, have been my favorite go to since they came out. I think they do better than any other patch, spray, or gel I have used so far.
