Setup, Compatibility & Care
Using these envelopes requires no specialized equipment or setup. Simply insert your A4 documents, ensure the items are pushed fully into the base of the envelope, and press the adhesive flap firmly across the top to create a secure seal. For optimal care, store the remaining unused envelopes in a cool, dry place to prevent the adhesive strip from drying out prematurely. Keep them away from extreme temperatures and direct sunlight to maintain the integrity of the press-seal adhesive over long storage periods.
