Nowadays, letterboxes not only have the function of receiving letters, but we also receive packages through them. When you order certain items online, they will be delivered to your home. When delivered, you often have to be at home to receive the products, or pick them up from the neighbors/collection point. But if you choose a parcel letterbox, you will still receive your parcels at home, even when you are not at home!
A postman can use the parcel letterbox to deliver the packages. How convenient is it that you still receive your packages while you are not at home. This way, companies can better adhere to 'ordered today, delivered tomorrow!'
Fortunately, the parcel mailbox is closed with a lock. Using keys or an entrance from inside, you are the only one who can remove the packages from the letterbox, so that the packages are safe.
What are the advantages of a large letterbox?
