Save time with our extra strong strip and peel technology. No water required. The security pattern tint assures that no one can see the insides of the envelope without tearing it. Feel safe that your private information remains private. Top Window is 1/2'' from the left and 5/8'' from the top of the envelope. Bottom Window is 1/2'' from the left and 2 2/8'' from the top of the envelope. Please refer to the product photo on the upper left of this page for the full display of the dimensions.
