Thank you for sending back an e-mail.
As we wrote previous e-mail, your racket’s grip is not modified at all.
Bridgestone told me that some stuff like silicone and urethane foam is usually injected into this kind of racket’s grip. We attached the picture of same racket’s grip end to this e-mail.
Please check it.
About another modification, Tennis 846 shibuya always check our used racket’s modification such as weight, balance and so on before selling them. So we think that your racket is not modified in principle.
We guess that this Bridgestone racket was not mated to you.
Sincerely
Tennis846 shibuya
