Maybe half that, tops.
Flensted Airflow 24 Mobile
This sophisticated mobile is handmade from a single piece of white sheet plastic, folded to create a spiral staircase. Spins freely and easily with the slightest air current. Made of hand-folded sheet plastic and a wooden dome. Hangs 18" tall by 10" wide. Comes fully assembled. Made in Denmark.
Considering the cost it was much smaller than I anticipated. I wouldn’t have purchased it if I realized it was pretty small.
