Ok so here is a side by side of the clone against my real kayfun 5 just to give you an idea of the comparison.
on the right is the real one and on the left is the fake, as you can see the labeling is dark blue and has a different bar code as well on the bottom of the box that the fake does not have. If you look closely at the SM on the drip tip you will notice that engravings are not the same.
On the real its more detailed and deeper than the fake one. The serial numbers are also not as detailed on the fake than the real one. lastly the box did not come with any paper work like the real one. but i must admit that the quality is amazing and even down to the boxes are identical in color, size and even height. i hope this will help others identify real from counterfeit. man this is insane as i would be so upset if i was the owner of SM as someone has gone to a lot of trouble to fake these. its disgusting to me that this is even going on for such a small item. but i am sure it turns out to be millions in fraud a year
one last thing the fake has sub two sticker on the box that the real does not have.
