The mailboxes used in The Court House, London were designed and manufactured by The Safety Letterbox Company Ltd. The mailboxes had to meet the strict guidelines set out by the project architects, based around the design style and dimensional characteristics of the products.

Each individual mailbox is engraved with unique numbering identification and infilled with long-lasting gold colouring. The gold infilled engraving matches well with the bespoke brass lock to give the product a high quality finish.
