This is a dedicated camera strap for the RX1M3. It was included with the camera, but I don't use it, so how about it for someone who is looking for one? I think it will fit the RX1 series. The width seems to be 18mm. I haven't unwrapped the white paper packaging, so I don't know the length. I think it's a general shoulder strap. Please refrain from price negotiations. Please understand that this is a used item, although it is unused, and purchase it.
