Peak Design Cuff Wrist Strap CF-BF-3 Purchased from Yodobashi.com in September 2025. I tried attaching it to a Sony α7RV once, but it didn't suit me, and I ended up using a regular neck strap. After attaching it to the camera once, it was stored in a dehumidified storage box, so it's practically like new. I think it's in good condition, but it has been used once, and there may be some oversights. Please refrain from bidding if you want a new item.
