Gluing - closing an envelope with such gluing is done by pulling off the strip covering the glue, putting on the flap and 
pressing on the envelope flap and it is already firmly closed. Fast, safe, clean, practical and convenient. Envelopes really 
store much better because the gluing is protected by the strip, lasts longer and does not stick to the envelopes lying below. 
In addition, envelopes with such gluing are easier to fill and maintain their validity (warranty).
