Eco-Friendly Mail Delivery Icon - Sustainable Postal Service Symbol #3758218 (License: Personal Use)

This minimalist black-and-white vector icon depicts a traditional postage stamp with perforated edges and an open rectangular center. Three horizontal wavy lines flow across the left side, commonly interpreted as water, wind, or emissions-suggesting ecological themes like carbon-neutral shipping or sustainable logistics. The design balances recognition (stamp) with conceptual messaging (flow/environment).

Used on websites related to green logistics, postal sustainability initiatives, carbon footprint calculators, or educational content about eco-friendly delivery methods; matches user intent for visual metaphors of “green mail” or low-impact shipping.
