Frequently asked questions

Practical Answers Before You Enquire

See all buyer questions →
Can I order 500 custom printed mailers?

Eligible Welltroy poly, poly bubble and metallic bubble mailer specifications start from 500 pieces per confirmed size, color and design. Send the quantity for each version so we can confirm its minimum. Splitting 500 pieces across versions does not automatically qualify, and full-coverage printing or a different construction may have different requirements.

Can I get a free mailer design draft within 24 hours?

Yes. Welltroy offers a free initial design draft within 24 hours after receiving a clear packaging and artwork brief. Send your product, size, logo files, print sides, colors and quantity. The initial draft starts the review; the final production artwork and specification require separate written approval.

Are samples free, and can they arrive within seven days?

Samples are free. Preparation can take as little as 3 days after specifications and artwork are confirmed. The delivery target is within 7 days of confirmation, depending on destination. Confirm the sample type and shipping arrangements, including any delivery charges, before dispatch.

See the sample and ordering terms, design and artwork checklist, and full custom mailer answers for the details behind these answers.
