They're made in the UK, in a factory on the banks of a river in Yorkshire! Our new glasses are made of Polycarbonate, a very tough material which is totally recyclable and virtually indestructible. They won't break if you drop or even throw them on the ground, but maybe don't try driving a tractor over one! The factory is only 4 miles away from us, so not many emmisions getting this fabulous product here! We've kicked off proceedings with our Bee, Pheasant, Stag and Heart designs. The design will never rub off, it's engraved by a highly expensive laser!
