This is a TT685 speedlight for Nikon cameras. It uses 4 AA batteries. It also has commander functionality with the Godox wireless X system. I have confirmed that it fires. It has many scratches. The case is torn and frayed, but I'm including it because it's useful for protecting the flash during shipping. The on/off switch feels a little loose, but it doesn't affect its use. Everything in the photos is included. The hot shoe terminal cover is not included. Batteries are not included. No claims/no returns accepted.
