What kind of baseball bats do most international baseball leagues use?

T-money asked:


I am curious to know what kind of baseball bats most international baseball leagues use. I know here in the United States that for the major league level, they use wooden bats and for the college level they can use aluminum. I’m trying to figure out what they use at the highest level possible for most international baseball leagues such as Japan, South America, etc. Any help would be greatly online pharmacy no prescription needed appreciated!
