X-Series is our Pro level maple bat. These bats come just like you see in the pictures. They are non Model specific so each bat can come in a different model. These bats are pulled from our pro production line for failing one of our 14 quality control points. The grain may be off or a slight defect ect. They are still great bats just not good enough for our professional players. So we decided to offer these as a low cost entry into maple bats. They sell in a pack of three! or go back to the shop and buy only one.
