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
