How about this for table tennis practice? This is a T-shirt I wore about 10 years ago when I was the advisor for the table tennis club in junior high school. I cut off the tag because it bothered my neck (photo 6), so I marked it as having some scratches and stains... but in reality, there are no stains. This is my (the coach's) lucky T-shirt that I wore when I participated in the National Selection Tournament (March) and the All Japan Junior High School Tournament (August). It has a JTTA-approved patch, so you can wear it in matches.
