Hot Wheels Monster Trucks Power Smashers

Large track (115cm) with the large and regular Monster track included.
It can be disassembled, shipped via parcel locker, and doesn't take up much space when disassembled. The loop has a winding mechanism that launches the small monster track to circle around the loop.
The start is given at the top, and then it's unknown which car will win.

Purchased a year ago, it's been gathering dust for a while, and we wish to make room for new toys.

The box, however, has not been preserved.
