Oversized LEGO flower
it's 8 inches tall, and the flowers are removable.
These are printed with pretty strong walls so they'll stand up to being displayed on a porch in the sun without much fading, but don't go throwing them at the wall
You could stack one on top of the other like the real LEGO piece, but the bottom flower won't fit on ALL the way if you do. it'll fit, but not as much as the other 5
