Arches Unit Block Bundle - 16 Pieces

I started using these arches to build bridges over our block roadways, and they fit perfectly without wobbling. The smooth, rounded edges make them easy for small hands to stack, and the set includes just enough variety to keep my four-year-old engaged for a solid hour.

These arches are the perfect size for a preschool classroom, letting my kids finally build doorways and tunnels instead of just towers. The set of 16 gives us just enough to make some pretty impressive structures, and they've held up to daily use.

My 3-year-old loves stacking these, and the arches are the perfect size for her little hands—they finally let her build tunnels and bridges instead of just towers. The wood feels smooth and sturdy, so I don't worry about splinters.
