These 3D wooden puzzles are really fun to put together and such a joy to see after! My Boys loved them! Now the puzzles are in their rooms as show pieces. They were easy enough to figure out how to put together without the instructions, and very sturdy. I don't know if the instructions were lost or not included. The boys have decided to paint them, since they are just plain wood. I can see the finished product being in our house for a long time! There are three different puzzles in the package so we put one together a night and the boys chose which ones they really wanted for their rooms. Awesome fun!
