HAPPYDAY 25 Pack FFP2 4-Layer Micro Dust Protection KF94 Face Mask, Made in Korea, Individually Packaged, White Small

Nowhere does it say it is a child size mask, but it is far too small for an adult.

it is potentially very good mask and it is exactly what I was looking for, but.. I am female with very small head size XXS and equally small face and it is too small for me! I can only assume it is designed for the child. I used it on a plane to Dubai, the straps were a bit too short and, therefore, after few hours it started to heart my ear badly. Also, it wouldn't cover my chin either and keep riding up as it was too small.

Very nice product. Even in a hot day sweating it is comfortable
