vistaprint mailer boxes

Searches for vistaprint mailer boxes usually come from UK sellers who want custom printed mailer boxes with their own artwork, in a size that fits their product and at a quantity a growing shop can manage. Custom Postal Boxes is a separate UK supplier of custom printed mailer boxes, manufactured in house in Wolverhampton with low minimum order quantities, free design support and free UK delivery.

What buyers comparing vistaprint mailer boxes usually need

Most of the enquiries behind this search are practical rather than brand led. A seller wants a box that folds up quickly, survives the post, shows a logo clearly and can be reordered in the same size next month.

It helps to compare suppliers on the same written specification. Ask for the internal size, the board type and thickness, whether print is available inside as well as outside, whether the boxes arrive flat, and what quantity the quoted price is based on. With those five points in writing, two quotations can be compared fairly instead of by headline price alone.

Mailer box features worth checking before you order

A well designed mailer has a lid that tucks in or seals with a peel off adhesive strip, front walls that overlap for extra crush resistance at the corners, and enough room for the product plus a layer of protection. Look for clean creases that fold without cracking the print, and check whether the supplier provides a template for your exact size so artwork is placed correctly on every panel.

Artwork, templates and proofing

Artwork errors are the most common cause of disappointment with printed boxes. Text placed too close to a fold can disappear into a crease, and a logo centred on the flat template may not sit centred on the folded lid. Ask for a proof that shows the box in its folded form, check spelling and web addresses carefully, and keep a note of your brand colour references so a reorder matches the first run.

Choosing sizes around Royal Mail formats

Mailer boxes are often bought by sellers who post daily, so external dimensions matter as much as the fit inside. Royal Mail large letters can measure up to 35.3cm by 25cm by 2.5cm and weigh up to 750g, small parcels up to 45cm by 35cm by 16cm and 2kg, and medium parcels up to 61cm by 46cm by 46cm and 20kg. A mailer that is slightly too deep for the format you intended can raise the postage on every order you send.

Check the current limits on the Royal Mail Tracked 24 size information and then choose a box that leaves room for your product, any insert and the thickness of the board itself. Ordering a short test run in your chosen size and posting a packed sample to yourself is a reliable way to confirm both fit and postage band.

Quantities, reorders and storing your boxes

Flat mailer boxes store in a small footprint, but a tall stack in a damp room will warp and become hard to fold. For reorders, record the exact internal size, board and print specification from your first order. Suppliers can then repeat the job accurately even if the person who placed the first order has left the business.

FAQs about vistaprint mailer boxes

Is Custom Postal Boxes the same company as Vistaprint?

No. Custom Postal Boxes is a separate business, a project of Vertex Packaging based in Wolverhampton, and it is not connected with Vistaprint. This page exists because many UK sellers search that term when they are comparing suppliers of custom printed mailer boxes.

What should I compare when choosing a mailer box supplier?

Compare the internal size, board type and thickness, print options inside and outside, how the boxes are supplied, the quantity a price is based on and whether design support is included. Written answers to those points make two quotations comparable, whereas a headline price alone can hide a thinner board or a larger minimum quantity.

Can I get mailer boxes printed inside and outside?

Yes. Custom mailer boxes from Custom Postal Boxes can be printed on the outside for branding and on the inside of the lid for a message, instructions or a pattern that the customer sees on opening. Free design support helps you place artwork correctly for the folded box.

What size mailer box do I need for Royal Mail small parcels?

A Royal Mail small parcel can measure up to 45cm by 35cm by 16cm externally and weigh up to 2kg including the box and padding. Measure your product, add room for protection and the board thickness, and choose a box that keeps the finished parcel inside that limit if small parcel postage is your target.

Can I order a small quantity of custom mailer boxes?

Minimum order quantities are low, which suits new shops, product launches and seasonal ranges. Ordering is quote based with free UK delivery, and pricing depends on the size, material and quantity you choose, so send those details with your enquiry.
