Easy installation: no tools and screws are needed to peel off the adhesive and to your door. It is strong enough to hold all your letters and small packages without peeling or moving. I believe your mail will be left in the bag fixed on the door. Suitable for most doors: whether your door is made of glass, metal, UPVC or wood, our mailbox catcher can be stuck. Every door is unique. Some doors don't have long and flat surfaces, so we have tested all kinds of ridges and surfaces to make sure it can stick to your door. Easy to access and open: it is very suitable for people who have difficulty in moving and can't bend down to pick up the post. Our easy-to-open latch has a unique design with a hanging part that is convenient to open the bag. Unlike other , it doesn't pull the whole bag off the wall to check your mail. Large capacity: it can hold most of your mail, and the extra space can hold magazines, small packages and many letters. Because the material is flexible, unlike a rigid cage, it can hold anything placed through the mailbox. Reduce airflow and protect your privacy: Because the fabric covers the slot, the airflow is reduced, and the peeping eyes can't see your home through the slot.
