Envelope Type Used
- LetterStream uses #10 window envelopes larger flat sized windowed envelopes.
- Window envelopes allow recipient addresses printed on the document to show through for accurate delivery.
Security Tint Explained
- Both our #10 window envelopes and larger flat envelopes include security tint (a printed pattern on the inside of the envelopes)
- The tint disrupts visibility, preventing the contents from being seen through the envelope.
How It Protects Your Information
- The security tint helps protect against both accidental exposure and intentional viewing of your documents.
- Even under bright light, the tint ensures that text inside is not readable through the envelope.
