I have purchased many Melissa & Doug products and the quality is usually excellent. However this puzzel is poorly made....at least the one I got is. The pieces are not clean cut so they are difficult to put together. And on many of the pieces the paper picture on the front is loose and peeling off the cardboard backing. That's the condition straight out of the plastic bag in the box. It's not like we have made this puzzle 10 times or anything. I purchased another one of these (Solar system floor puzzle) but haven't opened it yet. It better be of a higher quality than this one or I'll return them both.
