ic! berlin Vitan V.
ic! berlin's glasses are made of extremely flexible and lightweight 0.5mm spring stainless steel making them practically indestructible, yet soft enough to adjust by hand to achieve the perfect fit.
The steel used contains iron, carbon and chrome, as well as trace amounts of nickel but as a rule is suitable for people with allergies: thermoplastic Elastomer (TPE), silicon and acetate temple tips and nose pads prevent prolonged contact between skin and metal. Frame meets all DIN EN ISO 12870, ISO 12312-1:2013, ANSI Z80.3-2010 and AS/NZS 1067:2003 standards.
TPE and siliocone nose pads and elastomer temple tips can be easily bent to adapt to the shape of your skull, but acetate temple tips must be heated before adjusting; if you try to bend cold the acetate will break.
ic! berlin's revolutionary, patented interlocking hinge system means there are no screws to fall out or break. ic! berlin glasses can be dismantled and reassembled in a matter of seconds, by hand, without extra tools.
