Right, OP….. I’d love to take the piss and offer you £50 for them. But, as im feeling generous I’ll tell you what to do…..
What you have there is a pair of Zero 0.3’s
They are extremely rare and are very collectible, very much sought after by fellow Oakley collectors.
If they are in good condition they will go for a lot. If you have original box they’ll go for a lot more
Stick them on eBay, offer to ship world wide. Stick “rare” “vintage” “collector” int he title (of course Zero 0.3 too!)
If you’re lucky and they are in perfect condition you could be looking at a few hundred £
