Mailer & shipping boxes

Corrugated mailers printed inside and out — strong enough for courier, good enough for unboxing.

Mailer boxes overview

Our mailer boxes are E-flute or B-flute corrugated board with tuck-front closures, printed in CMYK on kraft or white liner. They protect in transit and still feel like a branded experience when opened.

Typical uses are e-commerce subscriptions, apparel, shoes and seasonal gift drops.

FAQ

Mailer boxes FAQ

Short answers to what buyers ask before ordering custom boxes.

Which flute should I choose?

E-flute (about 1.5 mm) suits most apparel and cosmetics mailers. B-flute (about 3 mm) is better for heavier items or long courier routes.

Can you print inside the mailer?

Yes, inside printing is common and adds a reveal message when the box opens.

What is your minimum order quantity (MOQ)?

We accept low MOQs for most custom boxes. Simple structures can start from a few hundred pieces; the exact MOQ depends on size, materials and finishes, and we state it on every quotation.

How long do samples and production take?

Samples take 5–7 days after artwork and dieline approval. Mass production takes 15–25 days depending on quantity and complexity. Shipping time is added on top.
