In an earlier purchase, I had bought the carrying cases for the Monster Trucks and Matchbox cars - On my grandson's birthday he was two handed wheeling the trucks and cars now securely stored. He loved the cases, and studied the trucks and cars closely noticing all their details. He knows them by name, and building quite a collection. Again, I was the Amazing Grandmother, knowing exactly what he wanted. Doesn't get any better. Always impressed with Mattel toys.
