3.875 X 8.875 Inch Envelope

Product details

Measuring 3.875 inches in width and 8.875 inches in length, this envelope strikes the perfect balance between compactness and capacity: it easily accommodates standard folded letters, slim brochures, gift cards, or small flat accessories (like jewelry or stationery samples) without excess bulk, making it ideal for first-class mail, event invites, or small business shipments. Its classic triangular flap design ensures a secure seal (compatible with glue, stickers, or self-seal options, depending on the variant) while maintaining a polished, streamlined look that avoids the clunkiness of larger envelopes.
