The listing, Tiered Auction: #12 Business Envelopes has ended.
These business envelopes measure 4.75" by 11". The #12 means they are larger than the envelopes people usually use. Also, they are manila colored, not white.
They are made by Quality Park Products Corporation and are 28 pound stock.
Here is how the tiers will work: every 1,000 credits will get you 25 envelopes.
< 1,000 credits: 25 envelopes
1,001 to 2,000: 50 envelopes
2,001 to 3,000: 75 envelopes
3,001 to 4,000: 100 envelopes
etc.
