Online reseller Begoina claims these tungsten-steel key holders are manufactured using the same grade of material that Rolex uses in its line of watches. The end that secures your keys and/or key fob rotates 360 degrees, which also allows it to neatly fold up when not in use. Included is your choice of logo fitted to the product, from popular brands to exotics such as Ferrari, Porsche, Rolls Royce, Bentley and Jaguar. Each is priced at $18 ($16 each when ordering three or more). Order from www.begonia.shop.
