This mailbox and post sleeve really make a statement when it comes to a mailbox. Large. substantial. The mailbox itself it a bit flimsy compared to the white vinyl post. Classy. Has mailbox, open newspaper holder underneath and a section behind the mailbox to out plants or flowers to make it look even more attractive. You need to buy a 4x6 post and secure it in the ground with cement. The vinyl mailbox slips right over the post. My husband and a helper installed it.
