Nope

Not being petty or anything but package only has 49 filters not 50.

Very convenient filters for on the go or when you need to protection in any occasion just replace old filter with new filter.

All were packed together wrapped in a packing foam sheet. Not very hygienic.

Very small. Will work in youth face mask. But not adult

These are just plain gauze cut in squares, not 2.5 anything

Took 2 long to get

As described. Delivered within delivery window. No issues!
