Butterfly Tenergy 05, black, used rubber. Purchased new and used for about 2 months, from September 27th, 2025 to November 29th. 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. As a point of caution, there is a spot on the tip where the sheet tore when I hit it during a Chiquita. I don't think it affects the sweet spot, so I don't think it will have any particular impact. The racket I was using was a Butterfly SK7 Classic. It's a racket with a blade size of 157x150. Please understand that this is a used item before purchasing. I plan to ship it via Yu-Packet Post, which will be sandwiched between cardboard to prevent bending and delivered directly to your mailbox. #1.9
