eWINNERMetal Camera Lens Filter (9 Pieces, Black)

Decent to good quality build. Fits well and the threading feels smooth. Definitely, a must-have if you own more than 1 lens with different diameters. All the pieces have the same quality.One thing to have in mind: these rings should be permanently attached to your lens, the thread despite being good quality can be annoying to fit since finding the starting position it's difficult. Overall totally recommended

Good for utilising one vnd filter or cpl filter to other lens with the help of these rings. Quality is also reasonable.
