Gel mask has a plastic smell [SEP] Ultimately this site is a great option. The sleep mask helps greatly keeping sunlight out. I will say that the gel mask has a strong plastic smell to it which I do not enjoy. It actually makes it unbearable to wear so I’ve only been using the sleep mask. If the mask did not have a scent to it it would be great. The gel when frozen feels great around your eyes and helps relieve any puffiness or it’s just relaxing if I have a headache.
