These glasses are not transparent and do not "shine" no. Looks like they have a porous texture on the surface or a silicone covering. So the glass is slightly blurred, as if he had been abraded. If you want a clean transparent glass and "brilliant" and that simply makes clean, that's not it. Whether through dishwashing machine or by hand: same final impression. The stroke color to the background, which is transmitted in the rest of the glass is cool.
