If you find yourself at a bar in Johannesburg or Cape Town, check out the coaster your drink is resting on.  If you’re lucky, it may be one that could save your life. The Reflector Protector was designed by the Y&R advertising agency in collaboration with Edward Snell & Co Ltd., a South African liquor company. When done drinking for the night, you peel off the top layer of your coaster and place it onto your clothes.  Your patch immediately turns into a reflective sticker that turns you 900 percent more visible than if you weren’t wearing it! Good idea, great execution and free.
