In addition to the square filters, I have now also bought the inexpensive magnetic filter holder set. I can only say: great. However, I am missing the possibility of getting ND 8 and ND 64 (magnetic) because only ND 1000 and polarising filters are available. A second glass-filled filter holder is included, which can be kept permanently with an adapter ring for a second lens size and still! fits into the super handy case. For the time being, this inexpensive set with magnetic holder is enough for me; if I have further requirements, I will probably switch to the "big" filter holder system from another manufacturer (approx. 400 euros with three ND filters). Which photographer doesn't know this "want to have?". In short: Riko Best's contribution on YT convinced me. Would I recommend it? Yes, to anyone who wants to work with grey filters now and then. LG

I am absolutely satisfied with the overall package price performance is definitely right here the magnet is sufficiently strong and I could not notice any gaps as described in other reviews the bag offers good protection and can be fastened well with the double Velcro fastener and the eyelet for a hook I would buy the magnetic filter set again at any time
