When I was that age my dad would come home from work and tell me someone had given him a "model train / slot car / other electric toy" at work but it needed a new motor or brushes or something to make it work, luckily they had some spare ones at his work that fit perfectly so he brought them home so I could repair the toy before I used it.Unagi label is applied by one of my sticker experts (aged 6 and 8).
I became an electrician just like my dad was, I wonder why.
