Is this a mask or a full costume?

It is a mask only. The green hair is part of the mask; clothing and makeup are not included.

Will it fit an adult head?

It is sold as an adult mask. Fit depends on head size, and full-head masks feel snug on larger heads.

Full-head masks rarely leave room for glasses. Expect the eye openings to sit close to the face.

Eye and mouth openings allow some vision and airflow, but peripheral vision is limited and the mask gets warm.

Keep it in a cool, dry place and avoid crushing the hair so the molded strands keep their shape.

It is an adult mask. For children, a smaller clown mask or face paint is a safer fit.
