## Long description

NC Koperty Envelope C4 NK (500 pcs) is a pack of white paper envelopes sized 229 x 324 mm, intended for mailing A4 documents either flat or folded once. These envelopes feature a gummed (water-activated) flap that creates a secure seal after moistening.

Key specifications
 Format: C4 (229 x 324 mm)
 Quantity: 500 envelopes per pack
 Color: white
 Closure type: gummed (water-activated) flap
 Material: paper
How to use
Insert the A4 document either flat or folded once into the envelope. Moisten the gummed flap lightly using a sponge, a damp cloth or by applying a small amount of water along the adhesive strip, then press the flap down firmly to ensure a full seal. Allow a short drying time before handling to ensure the adhesive bonds and the envelope remains closed during transit.
Usage recommendations
For secure mailing, avoid overfilling the envelope beyond its capacity and ensure the flap is evenly moistened before sealing. Use a rubber roller or press firmly along the flap to improve adhesion. For sensitive or important documents, consider adding a protective sheet or placing the item in a plastic sleeve prior to inserting it in the envelope.
