PicassoTiles 4 Piece Yellow Race Car Track Quarter Round Magnetic Tiles

The curve in these tiles makes the track way more fun than straight pieces alone, my son loops his cars around and around for ages. Magnets snap tight enough that the track doesn't fall apart when he bumps it.

The magnets are strong enough to hold together even when my son builds elevated curves, and the bright yellow really pops against the other colors.

These quarter round pieces finally let us connect the straight track into an actual loop, which my son had been trying to figure out for weeks. Only gripe is that four pieces isn't much on their own, so you really need an existing set to make them worthwhile.
