Ignore the reviews that this is fake, it is most definitely real carbon fiber.  I went to an upscale mall looking for a carbon fiber or some other kind of sleek  money clip, or minimalist front pocket wallet, and  was willing to spend some money  as I will hold onto these things for many year. prices ranged from $65-$300.  Forget about the $300 Montblanc clip, it was beautiful but still a little bulkier than I wanted, and Im not paying $300. I was most tempted to purchase an M clip,  but frankly, the sliding openers add quite a bit of bulk to the clip,  just not what I was looking for. There was a Tumi clip for $65, the dimensions were right but it was a little stodgy looking somehow, and I didn't like the big logo on it.  One nice thing about getting older is Im able to better resist impulses, and was able to leave the mall empty-handed when I didn't find the right choice. Spent a few minutes on Amazon, and found this clip, and not only was it a fraction of the price of any of the other clips, it is more comfortable, and quite likely more durable. Metal is just not as resilient as this material, and since my cash capacity can vary from flat broke to stripper on Sunday morning, that was a factor in my decision. The straight metal clips were all very tight to begin with, the m-clip was easiest to get money in but again, thats at the cost of the most bulk. I Currently have four cards and 14 bills in this carbon fiber clip, and its not maxed out, snaps right back into shape. Ill report back if my opinion changes but based on many of the other reviews i think thats doubtful.
