Butterfly Tenergy 05 black used rubber. Purchased new and used from December 6, 2025, to January 28, 2026. Practice frequency was 3 times a week, for about 2-3 hours each time. After each practice, I took care of it and protected it with a protective sheet. The sheet has deteriorated somewhat, but it is still in usable condition. The racket I used was a Butterfly SK7 Classic. It has a blade size of 157 x 150. Please understand that this is a used item before purchasing. It will be shipped via Yu-Packet Post, which will be placed directly in your mailbox, sandwiched between cardboard to prevent bending. #1.9#Atsu
