***PATENT PENDING PRODUCT – Be careful buying “knock off” Gascan Adjusters from one of these other 2 eBay sellers. I’m the original Designer*** This listing is for(4) custom cut 2mm thick acid freeFOAM ADHESIVESto better fit your pair of regular Oakley Gascan sunglasses. Oakley Gascan sunglasses are made of a new “O Matter” plastic that tends to flex more overtime. If your sunglasses are too big on your head, this is your only solution to”getting rid ofthem”. No glue needed. Simply peel and attach to clean surface. These Adjusters help retain the fitof your sunglasses more like the day you bought them or possibly better. I started making these for a friend who ownsa fewpairs of Gascans, but after some wear, wouldn’t fit snug (kept falling off on his face/head). They are cut to fit the inside dimensions of your sunglasses between the arms and the frames. You can use (2) of the (4), one on each side,for a better fit and comfort; or you could use all (4), two on each side,for the tightest adjustment. Whichever fits you best. If you have the Gascan S (small) sunglasses, in which the lensesare a little smaller than the regular Gascans; (2) out of the(4) pieces are the same dimensions as the regular Gascans. The remaining (2)must be cut (bottoms trimmed)to fit the dimensions of the Gascan S sunglasses better.I will trim them to fit for you. I’m not sure if thesecould work with the Asian fit Gascan, but you could probably cut (trim) them to fit. I think they are the same dimensions as the regular Gascans, but not certain. There are 3 different versions ofthese sunglassesout there; Gascan, Gascan S and Asian Gascan. Most people have the regular Gascan sunglasses though. If you have a different type of sunglasses and think you might need something like these Adjusters, I can send you (2) 1″ x 1″ pieces of material instead. Then you would be able to cut out your own design to make your sunglasses fit better. PLEASE BE AWARE, there aremany different kinds offake/replica Gascanscirculating throughout eBay. These Size Adjusters are CUSTOM MADE for 100% authentic Oakley Gascan sunglasses, no one else (including Oakley)make these for this particular type of sunglasses. Fake/replica Gascans say “OAKLEY” across the bridge of the nose between the lenses, or don’t have the “O” symbol on the arms. I’m not sure if these could work withfake/replica Gascans, but youmight be able tocut (trim) them to fit.
