Triangular hanging flower pots - no nails or wall damage required.

Small metal hooks are needed to be screwed into the bottom of each planter for assembly. I used the ones in the photo. 

Large hanging door hooks fit a typical door with 1.5in thickness. Hook itself is 3mm thick, note that not all doors will close with that thickness.

There are two files for the pots: one with textured finish and one without. 

Increase flow by at least 5% to prevent leaks.
