Tins are so much more than receptacles and storage. They hold memories on their outsides as much as inside. Vintage tins that survived time without much damage can bring a smile on any grandma's face even though she can't quite open the blessed thing.
Your choice of tins keep your kitchen organized and kitschy or modern, depending on the design and lids. You want the ones that twang loudly to hide your cake and biscuits.
