Perfect container for my collection of shells, semi precious stones and crystals. I was concerned that the inside was painted blue but its not.  Just as I hoped, its more like enamel, durable and high quality. The aluminum is substantial, polished shiny and nicely crafted.  You wouldnt think the item was made of aluminum if you didnt know better.  Very pleased. BTW, the color is a beautiful tealaqua blue, exactly the shade of blue I was looking for.
