FAQs

Our postal boxes are designed to be sent as either a large letter or a small parcel, depending on the size of the item. If you have a smaller item that could benefit from additional protection, you may want to consider a bubble-lined envelope.

Our postal boxes are hardy and robust enough to withstand international shipping, as long as the parcel has been properly sealed with high-quality tape. However, if you are posting delicate items or items that are at high risk of being damaged, you may want to avoid plastic mailing bags and consider adding additional protective packaging to ensure your parcel arrives safely.

If you are sending documents via the post, our range of cardboard envelopes can minimise your postage costs while also protecting your documents and making sure they remain neat and tidy. If you cannot fold or crease your documents (or if you are sending a larger paper item, like a poster) you may want to consider a cardboard postal tube to keep you documents and art in great shape.

If you want to store and organise a large amount of important documents, consider browsing our archive boxes that are perfect for keeping track of accounts or documentation and robust enough to make sure that your paperwork stays safe.

Padded envelopes include a layer of bubble wrap for cushioning, making them ideal for posting fragile or delicate items like electronics, cosmetics, or jewellery. Poly mailers are lightweight, water-resistant mailing bags best suited for clothing and other soft goods. Both are supplied with peel-and-seal strips for quick, secure sealing.

We recommend postal tubes or cardboard envelopes, depending on the item. Tubes are ideal for rolled items like posters or plans, while rigid envelopes work well for flat prints.

Yes - many of our postal lines are available in bulk quantities, and some products (like bubble envelopes and cardboard boxes) can be custom printed for branded dispatch. Please get in touch with our team us to discuss your options.

Protect Your Shipment With The Perfect Postal Packaging

Choosing the right postal box or envelope is essential to ensure your items arrive safely and meet Royal Mail guidelines. Our wide range of postage boxes, parcel boxes, and postal envelopes is designed to suit every need, from ecommerce fulfilment to personal posting. Whether you’re sending fragile goods, documents, or irregular items, our selection of post office boxes, bubble-lined envelopes, plastic mailers, and postal tubes offers protection and efficiency at every stage of shipping.
