Exactly as described but instructions are more for adults
Perfect for 6 year old but the instructions are definitely for adults. Great toy to just play with and put together how they want

Age appropriate for 5-6 year old
Bought for a 6 year old which was okay but don’t really think it would be challenging for an older kid. The storage box is great to keep the parts together.

Very small and lovable pieces
When you have all the pieces, this is a wonderful product. However, there are some small pieces that are very important for every build, and those small pieces fall off very easily. After using the first build once, one of those pieces fell off it, and now we can not build any of them at all because it is gone (and the seller does not sell or provide spares). If you are an adult, this might be more your bag, just brace for potential loss. I absolutely DO NOT recommend this for a child below the age of 15.
