I need the separated sealing strip. My printer usually seals the regular envelopes before I put something in them. I use them for business. I will purchase the security envelopes next time since the plain envelopes are slightly see-through.
Allows you to put stuff in it and seal just as a #10 envelope should do. Blank front permits address return address and stamp. Adequate space on rear for vari-coloured smiley-face stickers or witty sayings. Likely to work correctly world-wide (with appropriate postage applied). Not suitable for tie-dying or for use even temporarily as a goldfish bowl.
