Every Bonsai is different and you will not get the exact tree in the image which is meant to only represent the tree type and rough size. Most trees are categorized as small, medium, large, or extra-large although the dimensions are estimates. Many other factors determine how we categorize a tree. All trees are shipped in a bonsai pot, but not necessarily the pot you see in the picture.
If something like the tree height is a critical dimension to you, let us know.
