When I was young (a long, long time ago...) I had a train case that I played with and kept stuff in that looked sort of like THIS. I have no idea when I stopped using it or where it went to.
A few years ago my sister-in-law's mother was moving and I nabbed a blue train case from her that looks like THIS. Mine is nice and clean, and I use it to store my embroidery notions.
I've been looking at train cases on Etsy, and my favorites are these pink ones!!!
Pink Train Case 1
Pink Train Case 2
Pink Train Case 3
Pink Train Case 4
This last one is a completely different style, but look how stinking cute it is!!!
