Royal Mail prices in proportion to size and weight. Keeping an item within 353 × 250 × 25mm posts it as a Large Letter rather than a Small Parcel — often a big saving. Our PiP boxes are cut to sit inside those limits.

Common buyer questions
What packaging do I need for ecommerce orders?
A box or mailing bag sized to the product, void fill or bubble wrap so nothing moves, plus tape and a courier label. Right-sizing keeps postage and damage down.
Which boxes fit Royal Mail Large Letter?
Boxes within 353 × 250 × 25mm post as a Large Letter. Our PiP postal boxes are cut to sit inside those limits so you pay the cheaper rate.
What is the best void fill for fragile items?
Pair cushioning (bubble wrap) around the item with void fill (kraft paper or air cushions) to stop movement. Fill any gap larger than about 3cm.
Poly or paper mailing bags — which should I use?
Poly mailers are waterproof, lightest and cheapest; paper mailers are kerbside recyclable with a premium feel but less water resistance.
