Twice as nice! UPS offers resuable express envelope

Coolhunting.com reports that the UPS has introduced reusable express envelopes that have a second tape strip. In an effort to cut costs and promote sustainability, the company that's famous for touting brown may soon go green. UPS is already using recycled fibers for their shipping materials.
From the UPS website, redesigned and made from 100 percent recycled fiber with 80 percent post-consumer content, Reusable Express Envelopes reduce waste by allowing documents to be sent and returned in the same packaging. Now your customers won't need to locate an envelope to return documentation to you, increasing convenience and possibly reducing delays.
In a digital age where most documents are sent online, will this initiative help UPS gain a larger customer share?
