Pieza de inicio del laberinto de canicas

The fit is perfectly flush with the track pieces we already had, so the run stays stable even when my kid slams the next marble down. It’s the little things—like how the lip catches the ball without any hiccups—that make this the right first brick for our maze.

The hole at the top grips the marble just long enough for my daughter to line up her next piece, and it snaps onto the track with a satisfying click. We’ve rebuilt our run four times today, and this start piece has held up through every single change.

My son immediately knew what to do with it — he snapped it onto the track and sent his first marble racing down within seconds. The fit is snug enough that it doesn’t wobble mid-run, which honestly makes all the difference for a three-year-old’s frustration level.
