Mailboxshop24 offers letterboxes in various colors, shapes, materials and sizes. If you already know that you regularly receive for example, very large envelopes, you should already take this into account when selecting your mailbox.
It is important to select the correct size postbox and mail slot best suited to the size of post your normally receive. To make the selection a little easier, both paper and mailbox sizes are subject to specific standards. Basically, the postbox size should be slightly larger than the contents. If you have a large amount of post please consider a larger postbox. This not only looks better and more professional, it also protects the contents. You've probably already been annoyed about post that has arrived damaged and in poor condition.
