Hello there, This is Kazuma Aida.
This week, I had good practice session so for.
However, My arms and shoulders weren’t good after the session.
How come?

This is a practical item for tennis.

Get rid of a replacement grip, then stick with flax.
Finally, Wrap up a replacement grip.

I used to compare to 2 rackets
Same racket, Same string, Same tension.
And with flax and without flax.
I was like,
“It’s different things”
I felt a good vibration when with flax.
But, without flax, It’s almost pain.
If you struggled with a bad vibration.
You must use it.
Thank you for reading.
