I think it turned out looking a little bit like a building, so the continuation of the battery boxes will be others of different heights…a slightly shorter one for the AAA bats, and maybe a low one with a pull out drawer for the 9 volts. Maybe make it look like a little cityscape. (Slightly different lid treatments?) We’ll have to see what they want to do.
Those look great! I’m constantly turning around looking for batteries at our house, and this kind of thing would TOTALLY help clean-up our random odds-&-ends drawer in the kitchen. I love the idea for creating a cityscape out of these too—such a great idea!
