全天候型ホローブロック - 22個セット

My kids built a fort taller than themselves in about ten minutes, and I didn't have to worry about them dropping a heavy plank on their toes. The lightweight hollow design makes them easy for little hands to carry, but they're sturdy enough to hold up to some pretty wild building sessions.

The Poly+ material is a game-changer—these blocks survived a full week of rain in our backyard and still look brand new. My son can haul the whole set across the yard by himself because they're so light, yet they hold up when he stacks them into a fort.

The whole set is light enough for my four-year-old to haul across the yard herself, and the poly material has held up to constant rain without any warping. We've built forts and balance courses that last all week.
