I would say they are genuine if they are directly from Amazon. It is usually the 3rd party sellers that sell fakes.

Better have a word with Amazon then

Unisex Justin Wayfarer Non-Polarized Sunglasses

Just being from Amazon does not mean they are definitely genuine - they keep being caught selling counterfeits

​not at that time they were separate listing. i ordered the 1st ones on the 55mm description. got sent 51mm complained they replaced them with 51mm !!! phoned again told them the 54mm listing which was 68.50 and told them to sent them and argued they should be cheaper price. they agreed and price matched the 58 quid or what ever it was.
the glasses are great. only wear aviators normally but only worn these so far on my hols the aviators are still in their case.

ooh have they updated it now ?

Very misleading. Desc says 55mm, but at checkout they have shrunk to 51mm

​fake stuff sent back by people and them keeping the real one happens in every shop

Great price, just be aware that these are 51mm which is the smaller frame version. If you have a larger face it would be recommended to go for a 55mm frame

Remove all doubt and get yourself a genuine pair of Koyo Boms, ain't nobody copying these;

if you purchased how would you know if they are fake?

The brown are slightly cheaper too. With same company, and very well reviewed

Available for £54.15 from the international sunglass seller if you click other price options

Non polarised.

Wayfarer should be taken out of the title.

Are these designed by Justin Bieber?
