#10 Heat Resistant Window Pull & Seal Security Envelopes

It’s the old problem – you want to use window envelopes with your Stamps.com account, but traditional cellophane windows melt, risking putting your expensive printer on the trash heap. Don’t let that slow you down – skip the melt and use our heat-resistant #10 window security envelopes for all your bills and business correspondence!

• Special heat-resistant window does not melt when printing postage and/or return address using a laser printer
• The tinted pattern inside discourages reading sensitive information through the envelope
• With Pull & Seal strip there is no mess, no moistening, just peel off the strip and press
• 24 lb. white wove paper provides clear crisp printing
