Usage recommendations

For best protection, place fragile or easily creased items between a thin cardboard insert and the envelope. Avoid overfilling; keep contents within the stated maximum size to prevent tearing or damage to the closure during handling. Store unused envelopes flat in a dry environment to preserve shape and sealing performance.
