Have you ever encountered such a trouble? A set of exquisite vehicle body advertisements was designed for the fleet, but there were concerns that they might block the drivers' view and cause safety hazards. I want to post promotional information on the street-facing glass, but I don't want the store to become dim and depressing, losing customers. There seems to always be an insurmountable chasm between the "display effect" and the "spatial function" of advertisements. Today, the advertising material we are going to introduce - single-hole through-sticking - is precisely a "genius invention" born to solve this contradiction.
