Building Block Ejection Ball Run Toy Set with 3 Changeable Shapes

Put a buildable marble run in front of your buyers with the Kids Building Block Ejection Ball Run Toy Set with 3 Changeable Shapes — a plastic DIY building block set that clicks together into a working race track, then breaks down and rebuilds into three different shapes, so the balls roll, drop and eject along a new path each time.

Why this SKU earns shelf space

• Three builds from one box — the track rebuilds into three changeable shapes, so the same set delivers repeat assembly play instead of a one-time build.
• Ejection action keeps kids at the track — balls are sent rolling, dropping and ejecting along each new layout, turning a static block build into a moving race.
• 500–600 pieces per set — a substantial piece count that supports long build sessions and justifies the box size on shelf or in an e-commerce listing.
• Unisex, wide age spread — the set is listed for boys and girls across 0–24 months, 2–4 years and 5–7 years, so one SKU can sit in multiple planograms.
• Color box, 28×10×22 cm — a compact retail-ready package that presents well and packs efficiently at 48 pcs per carton.
• Building and STEM positioning — the DIY construction format fits educational and construction toy assortments, not just general play aisles.

What's included
