EVERY week, the Northglen News brings you ‘Things You Never Knew Existed’. This week it’s SlapSee – the world’s first sunglasses that won’t fall off  – they slap around your wrist so you’ll never lose them.

According to the inventors, the secret is the special hinged nose-bridge and the sprung steel arms which fold.

With three different frame colours, and a range of different ‘slap’ colours, the glasses can fold around your wrist, ankle, bike handlebars or just about anything else.
