Designer & Architect Files

More than a delivery drop box. 

Just as every family is different, every home is different, too—yet most delivery drop boxes on the market don't fit more than 20% of Amazon package sizes and lack accessibility features.

Our team set out to solve this problem. As a result, we invented the optimal modern home delivery experience.

Our team builds each package safe to order with your specifications, from a standalone curbside box model to elegant wall and fence inserts, and models made for multifamily properties.

We have designed tried-and-true ergonomic features for accessibility and fit in many different spaces—because everyone has a right to live life safer with less worry.

Our most popular model, the Box Gobbler, can accommodate 94% of Amazon package sizes while upholding your family's right to privacy.

In a nutshell, our package safes are genius made simple.

love it

"I love this mailbox." Those are the words I say to myself ever single time go out to check the mail. It's so well made, and a beautiful design celebrating simplicity and security. Feels solid. I just love, love, love.

great box

I have had several locking mailboxes over the years but this is the best I was a little bit shocked at the price but I wanted a mail box so I decided to get it. I am definitely glad I spent the extra money it is heavier and far better constructed than the past mailboxes I have owned well worth the price.
