Cubic Fun 3D Puzzle Model SouvenirNavenavi T4019h

Is it suitable for a 3-4 year old?

I am putting together Queen Anne's Revenge. I get confused on parts which side goes up on the piece. Company needs to make it clear. Any advice?

Hi, is there a way to get booklet instruction with instructions? Kids messed up some parts, we can’t assemble it. Thanks!!

Can you change the batteries after full assemble?
