Large Letter Postal Boxes – Royal Mail PiP Size

Slim cardboard postal boxes sized to fit Royal Mail's Large Letter limits, so you pay Large Letter postage instead of parcel rates. They fit through a standard letterbox, so there are no missed deliveries or trips to the sorting office. Ideal for posting fabric swatches, samples, needles, tools, pins and other small, flat items.

• Letterbox friendly: delivered straight through the door.
• Strong corrugated cardboard: more protection than a padded envelope.
• 100% recyclable and biodegradable.
