PicassoTiles 4 Piece Blue Race Car Track Quarter Round Magnetic Tiles

These quarter round pieces finally let us connect two track sections at a 90 degree turn instead of a dead end. The magnets snap together firmly enough that my daughter's whole loop stays put when she bumps the table. Being able to buy just the curves instead of another full set is what sold me.

My son already had a starter set, and these quarter rounds finally let him curve the track instead of just building straight lines. The magnets are strong enough that the curves hold together even when he's racing cars over them.

The quarter round pieces snap in perfectly to make smooth turns on our track—my kids love the bright blue color and how easily they connect.
