Quadruple Units - Unit Blocks - 4 Pieces

My preschool class has been using these for daily tower-building challenges and the blocks hold up perfectly against constant stacking and knocking down. The uniform thickness makes them easy for small hands to balance in complex structures.

These are the exact right size to bridge the gap between our smaller unit blocks, and my kids finally stopped fighting over the big pieces. The wood feels solid and squared-off, so the taller walls they're building don't wobble at all.

My kid's towers are way more stable now that we have these larger blocks to use as a solid base. The wood finish is smooth with no rough edges, which is a relief. I just wish they sold these in a bigger set, as four pieces disappear quickly into a busy playroom.
