As far as envelopes go, nobody makes them smaller. We inventory small envelopes by the millions, down to 1”x 1”. We can also custom manufacture small envelopes to your specifications, including printing in up to 4 color process and choice of paper (anti-tarnish or high water resistance, for example).
We also inventory square envelopes up to 7″ x 7″. If you need a square size not on our shelves, do not despair as we can easily create the exact size you need. Turn around time is approximately 5-7 days, so you need not be concerned with delivery time slowing down your project. Flaps can be gummed or ungummed, although in sizes smaller than 1-1/2″ x 1-1/2″ we only offer ungummed flaps.
We stock #1 coins (2-1/4″ x 3-1/2″) up to #7 coins (3-1/2″ x 6-1/2″) in 24# white wove and 24# Brown Kraft paper. We manufacture millions of coin size envelopes annually, and many are made from paper that is other than 24# white wove. For instance, colors, Tyvek®, Orca™ (low cost substitute for Tyvek®), translucents, metallics, anti-tarnish — take your choice of substrates, as long as we can fold it we can make an envelope from it.
