Supplier's note

  1. Technical Breakthroughs:

    • Interlocking durability: The reinforced peg-and-socket design (vs. industry-standard snap-fit) ensures 20% stronger connections for complex builds.
    • Material safety: CE/EPR certifications guarantee non-toxic, BPA-free plastics, exceeding EU toy safety thresholds.
    • Gear integration: Precision-molded gears (±0.5mm tolerance) enable smooth mechanical motion, ideal for teaching cause-and-effect relationships.

  2. Version Selection Guidance:

    • Base Model: Optimal for younger children (2-6y) focusing on color sorting and basic construction. Its lightweight plastic ensures safe handling.
    • Advanced Model: Targets 4-9y users exploring gear systems. The added molds and 15% more gears allow building functional pulleys or cranes.
    • Pro Model: Designed for 7-12y engineers, its electronic gears (30% more than base) and sensor compatibility enable programmable machines, such as automated conveyor belts.

With the Pro’s motorized components, you can create dynamic structures like rotating Ferris wheels. The Advanced model’s expanded gear set lets kids replicate real-world machinery. Choose the Base for foundational play or upgrade to advanced features for STEM mastery.
