Mekano
"These are very expensive toys, Marvaine. While they are built to be as safe and childproof as possible, you need to handle all of the parts with utmost respect. Treat them like how a real mech designer treats his own mechs. Do you understand, my son?"
"I understand, papa." Marvaine cutely said. He looked so adorable when he pretended to be serious.
It didn't take long before he turned back into an overeager kid. He was rubbing the side of the boxes as if he couldn't wait to unlock them and piece together his first toy mechs!
Ves could understand the kid's enthusiasm. Which mech-obsessed boy wouldn't want to play with Mekano? Even those that wanted to become mech pilots rather than mech designers when they grew up played with them if possible.
While not every child was interested in the intricacies of mech design at their ages, they all loved to put together a finished Mekano that they could play with themselves!
