Is this an official Scream mask?

No. It is a generic Ghost Face-style costume mask, not a licensed Fun World or Scream product. The look is close, but collectors will notice differences in the sculpt and finish.

Will it fit an adult?

It is sold as one size for most adults and teens. The hood covers the head and neck, but fit varies, so larger heads may feel snug.

Can you see and breathe through it?

The eyes are hollowed out and the description calls the construction breathable. Visibility through the eye holes is limited, so move carefully in dark spaces.

The mask with its attached black hood. The hood is part of the mask, not a separate piece.

Is it good for a costume party or haunted house?

Yes. It is lightweight enough for long wear and the hood gives a full-head look. It is a costume piece, so treat it as disposable rather than a durable prop.
