The snail puzzle is flat and requires more maneuvering to get out--so definitely for someone who is a little older (or with adults help to remove and put back). This is clearly shown in the product images though, so I was not surprised by this.
It also comes with a bag which is really nice. I do wish the bag was SLIGHTLY larger because it is slightly too small to fit the square puzzle in, so only the blocks can go in it. It has a pull at the top to tighten it as well.
Overall, very pleased with this and will be using this with the kids I work with.
