Looks like 3D printed. Not quite typical plastic, there are threads hanging from it. I'm not sure about the quality and for this reason I won't be drilling holes in my mailbox to install it, I will do it with double sided tape or liquid nails. I don't think it's worth the $17 I paid for it. I wasn't expecting anything like the strange material it's made of. I love this concept and hope it works well and holds up in the Florida weather. I will keep updating my review after 3 months
