Beautiful wood blocks in a modern palette. They look nice enough to leave out in the living room, which is half the battle for getting kids to play with blocks.
Honest drawback: Non-magnetic, so towers topple more easily than with Tegu's magnetic line. Some kids find that frustrating, others find it more satisfying.
