The Columbian #8 5/8 Security Envelope is a great addition to any office. These business envelopes are made of 24 lb white wove paper with side seams for a professional appearance. The combination of sticking them together and the glues automatically sticking and sealing is overall very nice but it needs to be done in a better way, that is other than the way it is folded currently.

The unique double flap design allows you to simply raise the lower flap and press to seal. The plastic windows are also very secure & the interior of the envelope has a security pattern so it’s very hard to read the enclosed information. These are a great addition to any office.
