I like the tins, but they are a complete waste to me. I have a whole slew of them under my bed. I store my toys in my nightstand. I don't feel like getting down on all fours to look under my bed for that one special toy!
I only have one toy in a tin and I'm currently storing it in there. I imagine if I end up with a whole bunch that'll change or something else will get stored in them so they aren't wasting so much space.
