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.
Proper unit blocks, the kind every good preschool classroom has, made from reclaimed rubberwood. PlanToys says they use formaldehyde-free glue and water-based dyes.
Honest drawback: Fifty blocks is a starter set. Classrooms use hundreds.
A silk cape becomes a superhero, a queen or a night sky. Open-ended dress-up that folds into a pocket and doesn't steer kids toward any one character.
Honest drawback: Silk needs a gentle wash. It's a cape, not a costume, which is the point but may disappoint a kid who wants Elsa.
