Description
Our White PIP Boxes bring together the postage savings of a Large Letter with the polished presentation your brand deserves. Designed to meet Royal Mail's Pricing in Proportion dimensions, they're the smart way to send cosmetics, jewellery, accessories, small gifts and subscription items at the lowest possible cost.
The bright white exterior instantly elevates every delivery, giving a clean, premium feel that brown cardboard can't match. It's the perfect blank canvas for your branding, taking stickers, printed labels and stamps beautifully, so even small orders arrive looking considered and professional.
Slim enough to pass through a standard letterbox, these boxes mean customers get their parcel even when they're out, cutting missed deliveries and redelivery hassle. Inside, rigid corrugated board keeps contents flat and protected, while the secure tuck-in closure holds everything firmly in place throughout the journey.
Offered in a wide selection of sizes to suit a range of products, and manufactured in the UK from sustainably sourced, fully recyclable cardboard. Supplied flat-packed to save storage space and quick to assemble, with pack sizes to suit everything from occasional gifting to daily fulfilment.
