I have some train cases like that for makeup as I have an extensive makeup collection. Usually the little top parts that you see (the parts that come out to reveal the larger portion) are VERY tiny. I doubt they would hold any toys. They hardly hold more than three small eyeshadow pots and that's if I put them on their sides.
is my storage set up. The footlocker can be found at WalMart here
and the chest like thing can be found at Target here
. I don't know how big your collection is (as mine is quite large you might notice from the photo LOL). The chest offers some ability to sort better than the footlocker does. However the footlocker locks while the chest does not.
