3up 1099 Double Window Envelope (Moisture Seal)

Moisture-seal mailer for 3-up 1099, 1098 and 5498 forms

This double window envelope covers any 3-up recipient form in the 1099 family — 1099, 1098 or 5498 — printed on the standard 3-up layout. A moisture flap closes with a lick and press, and a security tint plus cellophane windows keep taxpayer ID numbers and payment amounts private during mailing.

Fold the printed recipient copy so the address sits in the top window and the payment or account detail sits in the bottom window, then moisten and press the flap. Software output varies slightly between vendors, so request a free sample before a full print run if you’re not certain of the fit.
