All PlanToys® are made with clean, natural rubberwood from rubber trees which no longer produce latex.
To keep the rubberwood pure, no fertilizer is added to the soil for three years before the trees are cut.
To strengthen the wood, PlanToys® uses a special chemical-free kiln drying process.
PlanToys® does not use dyes containing lead or any other heavy metals.
They use only safe, non-toxic water-based dyes on all of their toys
