Letterman XXL free-standing letterbox - the one with the porthole The Letterman XXL free-standing letterbox has been planned down to the smallest detail. It has plenty of space for large-format mail and a compartment for newspapers and magazines. A practical flap closes the compartment and the newspaper is protected from the rain. In addition, the porthole allows you to see immediately whether there is any mail in the box. A matching post measuring 8 cm x 4 cm x 144 cm is included in the delivery.
