I have 2 colors of these, they do differ in height and design slightly!
Each one holds 3 spheres at 3 different levels, the tiers are in a triangle.
Twisted Silver: 4.5" tall x 4" x 4" x 4" holders are 41 mm
Gun Metal: 4.25" tall x 4.25" x 4.25" x 4.25" holders are 43 mm
I did include a picture with spheres on one so you could see how they are displayed! ***The spheres are all sold separately***
