Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • STEM Education & Creative Play: Designed for children aged 2-4, this building kit promotes problem-solving, fine motor skills, and creativity through assembling structures like vehicles, buildings, and figures using interlocking ABS plastic rods and joints.
  • Modular Construction: Enables the creation of dynamic models such as moving vehicles (with wheels) or static structures, fostering hands-on learning in engineering and design basics.

Key features

  • 1. Eco-Friendly Material Technology

    • With eco-friendly ABS plastic, ensure safety for children while minimizing environmental impact* compared to non-recycled materials. The non-toxic composition adheres to strict safety standards like REACH and ASTM F963-17, offering peace of mind for parents.

  • 2. Modular Interactive Design

    • With a modular interlocking design, children can assemble endless creative structures* (e.g., vehicles, buildings) faster than with traditional block sets. The varied cylindrical rods and joints allow intuitive building, even for young hands.

  • 3. High-Capacity Performance

    • With 160 pieces included, build intricate and durable structures* (20–30% more components than average kits for ages 2–4), enabling complex STEM-inspired projects like bridges or vehicles.

  • 4. Versatile Scenario Solutions

    • With STEM-focused educational design, support early learning in engineering and creativity* for both solo play and group activities. The theme versatility (buildings/transportation) adapts to diverse play scenarios, enhancing problem-solving skills.

  • 5. Comprehensive Safety Certifications

    • With certifications like GCC, ASTM, CE, and BS EN71, parents can trust rigorous safety compliance* compared to uncertified toys. Meets global standards for child safety and chemical-free materials.
