Crystal Optics 58mm UV, Polarizer & FLD Deluxe Filter kit (Set of 3 + Carrying case)

I bought this set through the seller New Harbor and they were advertised as Crystal Optics and even had the real Crystal Optics part number. A Neewer box showed up with a bar-code sticker on it that said 'Crystal Optics 3 pc. filter set'. Each filter said Neewer on it and they looked fine but upon further inspection I found that the FLD filter was plastic and not optically clear. The polarize filter and UV filter were both glass but the UV wasn't nearly as good as my Zeikos UV filter. It looked like plastic and wasn't very clear but it was actually glass. The polarize filter made objects far away blurry and the center of the pictures were blurry too. The description for the Neewer 3 pc. kit says that all 3 pieces are 100% glass so I'm not sure how my FLD was plastic. New Harbor might have gotten counterfeits or something. I'd avoid buying this set on here unless you ask the seller to verify the part number before buying. I have to return these now and buy the Zeikos brand kit, which is $8 more but well worth it.

These are not actual crystal optics filters, they are from Neewer. I complained to Amazon and they fixed the matter on my end...however I'm not sure why this is still up. The filters themselves look fine for a low-end filter, I haven't actually tried them out yet other than to check that they fit my Nikon 50mm f/1.4 lens. The container is actually pretty nice, I'm using it instead of one I purchased with a set of filters for my other (smaller) lens.
