In addition to carefully selected materials and high-quality craftsmanship, the issue of safety is of highest priority at HABA. Kullerbü products, like all HABA wooden toys, pass through our in-house quality assurance as well as external test procedures. All Kullerbü balls have an extra large diameter of 4.6 cm/1.8 inches, so that they cannot be swallowed by children, especially by those under 3 years of age.
