165×100mm #1 Envelope — Custom Manufacturing Options

The #1 envelope (165×100mm) is the smallest standard Chinese envelope size — perfectly sized for business cards, small greeting notes, gift tags, and compact RSVP cards. At 165×100mm, it provides a neat, pocket-sized format that adds a touch of formality to small enclosures that might otherwise be handed over loose. Common applications include business card mailings with a branded cover letter, mini gift card envelopes for retail and e-commerce packaging, appointment reminder cards for medical and beauty clinics, and compact thank-you notes for hospitality. Despite its small size, the #1 envelope supports the full range of our manufacturing capabilities — from simple unprinted kraft to fully customized versions with foil-stamped logos, embossed patterns, and peel-and-seal closures.

Typical use case: Business cards, small greeting notes, gift tags, compact RSVP cards

Frequently Asked Questions

What is the minimum order quantity (MOQ) for custom envelopes?

Our standard MOQ is 1,000 pieces for custom printed envelopes. For custom sizes requiring a new cutting die, the minimum is 2,000 pieces. Specialty finishes like foil stamping start at 500 pieces. If you need a trial order, contact us — we accommodate flexible quantities for first-time clients.

What is the production lead time?

Standard production takes 7–15 business days for custom printed envelopes. Custom sizes requiring die fabrication add 3–5 days. Rush orders are available and can reduce turnaround by 30–50%. Your quote will include an exact timeline based on your specifications.

What file formats do you accept for printing artwork?

We accept AI, EPS, PDF, CDR, and high-resolution TIFF/PSD files. For full-color printing, please provide CMYK color mode at 300 dpi minimum. For spot color jobs, specify Pantone codes. Include 3 mm bleed and keep text 5 mm from trim edges. Our prepress team reviews every file and provides a free digital proof before production.

Can I get a sample before full production?

Yes — we provide free digital proofs for every order. Physical pre-production samples are available on request (sample cost is credited toward your production order). Samples typically ship within 3–5 business days. This is the best way to verify paper feel, print quality, and finishing before committing to a full production run.
