4up W-2 Double Window Envelope – Quadrant (Self Seal & Tamper Evident)

Tamper-evident closure for 4-up quadrant W-2 mailings

When a mailing needs proof it wasn’t opened in transit, this quadrant W-2 envelope combines a self-seal flap with tamper-evident cuts. If someone tries to reopen the flap after sealing, the cuts leave a visible mark, which matters for HR and payroll departments handling sensitive wage data. Both windows keep their standard security tint and cellophane glazing.

Fold the 4-up quadrant statement so the address block lines up in the top window and the wage detail lines up in the bottom window, then press the flap to seal. Order in multiples of 25, and request a sample first if you haven’t matched this envelope to your quadrant form before.
