Colorless Coke Can

"A convex logo substitutes colorfully sprayed can. Naked can help to reduce
air and water pollution occurred in its coloring process. It also reduces
energy and effort to separate toxic color paint from aluminum in recycling

cans will be saved. Instead of toxic paint, manufacturers process aluminum
with a pressing machine that indicates brand identity on surface."
