Material: white paper
Pack size: 50 envelopes

How to use
Insert folded documents or print materials into the envelope so they lie flat and align with the envelope edges.

For bulk mailings, stack envelopes evenly and use automatic sealing equipment if compatible; otherwise, seal each envelope by hand following standard mail-preparation procedures.

Store envelopes in a dry, cool place to prevent moisture-related warp or adhesive degradation. For important documents, consider an inner protective sleeve or additional padding to reduce bending during transit. Check postage rates for C5 envelopes to ensure correct mailing costs.
