Very poorly constructed, I have no idea why they chose to omit a swivel pin to connect the two pieces together.

It has 2 pins like a wristwatch band, tricky to insert them so it will pivot

Be careful while assembling the flap in the lid (mine came in two pieces), the pins are insubstantial and look like they could be easily damaged.

The only problem is that flipping the door knocks the cover off the top, and when it falls onto the desk, the pins pop out and have to be re-inserted
