ファーガス 木製ビー玉コース用スパイラルディスク

My grandson’s eyes went wide the first time the marble hit this spiral and twirled down instead of just dropping—such a small piece, but it completely changes how the run plays. The wood feels lovely and solid in hand, exactly what I’d expect from a German-made toy. This might be our favorite access

The spiral design makes the marble spin in a satisfying way as it passes through, and the wood feels smooth and sturdy. My toddler loves watching it loop around before continuing down the track.

My kid loves watching the colorful spiral pattern as it rolls down the track, and it fits perfectly with our existing wooden marble run. The only reason I’m giving 4 stars is that it’s a bit pricey for just one small accessory piece.
