Common questions
Are these envelopes compatible with standard mailing requirements?
Yes. These 4 1/4" x 2 1/2" envelopes meet USPS standards for small flat mail when sealed properly. The gummed flap provides reliable closure that satisfies postal service requirements for secure sealing without additional tape.
How many envelopes are in each case, and what is the cost per unit?
Each case contains 5,000 envelopes, making this an economical bulk solution for high-volume mailers. Purchasing by the case significantly reduces per-unit cost compared to smaller quantities, improving operational efficiency for mailrooms and distribution centers.
Will the gummed seal hold securely during handling and shipping?
Yes. These envelopes feature heavily gummed flaps engineered for industrial-strength sealing. The 28 lb. kraft paper resists tearing and puncturing, ensuring contents remain secure throughout the mailing and delivery process without requiring additional reinforcement.
Can I reuse these envelopes or are they single-use?
These are designed as single-use envelopes. Once the gummed seal is activated with moisture and dried, the adhesive cannot be reactivated. For cost-effective high-volume operations, the bulk case pricing makes replacement economical for each mailing cycle.
