My toddler keeps grabbing these arches to build little tunnels for her toy cars, and they hold up great even when she stomps on them mid-play. The open-ended design means we've used them in the sandbox and on the grass without a single crack.

I was skeptical the tall arches would survive my two kids’ daily stomping, but these pieces are seriously tough and hold up great on the patio. They’ve turned into tunnels, bridges, and even a mini fort in the grass.

We’ve had these out in the backyard every day for a week and the pieces still look brand new, even after being stomped on by my three-year-old. The taller arch shape is perfect for making tunnels that she actually crawls through, and I love that they work just as well in the sandbox as on the grass.
