Do you want to ask "What should I do if there is no mark on the butterfly racket handle?" Use racket marker pens and use colored tape.

1. Use a racket marking pen: Purchase a racket marking pen specially used to mark the racket handle, and draw your favorite logos and marks on the racket handle for easy identification.

2. Use colored tape: Use different colored tapes and wrap them around the racket handle. Each color represents a different racket and purpose to distinguish different rackets.
